Studying clothing consumption volumes through wardrobe studies: a methodological reflection

Authors: Irene Maldini, Vilde Haugrønning and Lucrecia de León

Abstract

This paper introduces the relevance of volume-centric research in studies of clothing use. The global production of garments has grown dramatically in recent decades, bringing along significant environmental challenges. However, knowledge is lacking about why people deal with clothing quantities in such varied ways, and what leads some of them to overconsumption. A review of wardrobe research methods shows that there are various approaches to studying garments going in, around, and out of wardrobes. Gathering qualitative insights about specific garments, such as favorite garments, has been quite common. However, in order to advance knowledge about clothing consumption volumes, it is important to look at the wardrobe as a whole and include quantitative aspects. This paper reflects on what approaches and techniques can be used to that end. The reflections are combined with lessons learned from a pilot wardrobe study conducted in Uruguay, Portugal and Norway in 2022 with 20 respondents, concluding with recommendations for volume-centric methods in future wardrobe studies. Rigorous accounts of all garments owned should be combined with registration of items going in and out of the wardrobe over time in order to link accumulation to production and waste volumes. Methods connecting garment quantities with practices of daily use are particularly valuable. One example that has proven successful is piling exercises, a technique where participants are invited to categorize garments in groups according to specific criteria.

Deep diving into wardrobes provides important knowledge on clothes and their environmental impact

Authors: Vilde Haugrønning, Ingun Grimstad Klepp and Anna Schytte Sigaard

Norway leads the way in methods for studying the use of clothing. This is knowledge that is important in sustainability studies of apparel.

How many clothes are there in our wardrobes? What is used a lot and what do you seldom wear, and why? Which clothes have the largest environmental footprint? What causes clothes to be cared for and repaired?

There are many unanswered questions when the desire is to understand the connection between the consumption of clothing, and climate and environmental impacts. We need to understand why someone has a wardrobe full of clothes and still nothing to wear. To answer these questions, methods that can reconcile the concrete material with the way we use, buy, repair, launder, choose and not least throw away clothes, are required.

The method called “wardrobe studies” is very central in studies of clothing’s environmental impact. Consumption Research Norway (SIFO) at Oslo Metropolitan University has been at the centre of the development of these methods for 23 years. Today, the method is included in research, teaching, product development and design worldwide.

Research in people’s homes

The method involves the researcher and informant going through the informant’s wardrobe piece by piece, together. In some studies, the entire wardrobe is reviewed and in others, selected parts such as passive clothes, leisure and sports clothes, or favourite clothes are specifically studied. When the clothes are reviewed, the researcher asks the same questions for each garment. This gives us opportunities to analyze differences in the way different garments are used.

The method is time-consuming but provides detailed and reliable knowledge. Ideally, we do this at the informants’ homes and thus also gain knowledge about details around the organisation, storage, laundering and care of the clothes.

Clothes are complex

Wardrobe studies are particularly suitable for studying practices that we often take for granted. The practices are important to understand in order to gain better knowledge of consumption patterns, and thus how they can be changed in a more sustainable direction. The special feature of the method is that the clothes are at the centre of the analysis.

Clothes are very complex materially, socially and culturally. They are made from most types of materials, from animals and plants, including metal and chemicals and increasingly plastic. They are used to camouflage the body, keep it warm, decorate, protect and show belonging to cultures, groups, places and positions in society. Clothes are important for self-respect, security and social participation.

In order to embrace so many different aspects and see them in context, methods are required which have the capacity to connect the actual material with the practices and their many different meanings, both for the individual and society.

What properties do the clothes have?

Wardrobe studies lead to more knowledge about the use of clothes. This stands in contrast to studies that are concerned with clothes related to fashion, often understood as the novelty value of the clothes. In such studies, some things are often excluded, namely the material properties of the clothes, as well as all the nuances in the relationship between the wearer of the clothes and the clothes themselves, and the interplay between the clothes in the wardrobe.

After conversations with people about clothes over several decades, we have rarely heard informants say that fashion is important to them, and it is much more common to say the opposite. Fashion is an aspect of our clothes, but for most people, there are completely different reasons for both what you buy and what you wear. Fashion can make it difficult to find something you like in the store, such as the colour you think suits you, or a shape that is perceived as flattering.

Few know how many clothes they own

To capture the material in wardrobe studies, various techniques are used to obtain information about each individual garment such as photos, interviews, registrations and technical analyses. This gives the advantage that the information becomes concrete and tied to both the material and social aspects, and thus not so dependent on words alone.

Clothing habits, like other parts of our daily lives, are something we don’t usually think about. Therefore, they are also difficult to put into words in a conversation or interview situation. It is easier to describe the clothes and how they are used when we talk about specific garments. It will then be possible for us researchers later to see the relationship between the clothes and the wearer, and pursue what lies behind the words.

Very few know the average age of their own wardrobe or how many clothes they actually have. We ask people about what they know and have a relationship with, but compile the information ourselves with national or global averages, or qualitatively based interpretations.

Knowledge to inform policy

Today, SIFO has several ongoing research projects with wardrobe studies: CHANGE, Wasted Textiles and Belong, all funded by the Research Council of Norway. Here the wardrobe studies are used to study how we use clothes for different occasions and the importance of variation in clothing habits, how we can reduce the amount of textiles and specifically synthetic textiles, and the importance of clothes for belonging.

In all projects, wardrobe studies contribute to important knowledge about the importance of clothing and textiles in our everyday lives. This knowledge is crucial to developing policies capable of drastically reducing climate and environmental impact, and at the same time ensuring everyone in the population has access to good clothing.

An important challenge in the work with clothing and the environment has long been very inadequate life cycle analyses (LCAs). Without knowledge of lifespan, disposable products are compared to clothes that are worn 500 times or more.

No one would argue that such a use of LCAs is correct, but going from this point of departure to finding methods to include lifespan in LCAs of environmental impact, is quite a challenge. SIFO has further developed the wardrobe studies method in a quantitative direction in order to obtain knowledge about global clothing habits suitable for such analyses.

Consumption is important

In these studies, we work with detailed information on 53,461 garments which gives the opportunity to ask questions about, for example, differences between different types of garments, fibres or what the clothes are used for. This is very relevant when the EU is now developing a new labelling scheme, the Product Environmental Footprint (PEF), which will include textiles. SIFO, therefore, contributes to the development of the rules specific to clothing in this labelling scheme. There, as in many other contexts, it is difficult to get the impression that consumption is important.

The work with wardrobe studies shows that in research it is not only important to develop good questions, but that the methods must also be adapted so that we researchers are able to deliver the knowledge that society needs. Climate and environmental problems cannot be solved without knowledge of people, society, politics and regulation. It is urgent to take the fact that we humans have created the problems seriously, but that we can also solve them. For that, we need more knowledge about ourselves and our habits and the way we use products that burden the climate and the environment a lot, such as apparel.

Local clothing: What is that? How an environmental policy concept is understood

Ingun Grimstad Klepp, Vilde Haugrønning & Kirsi Laitala

The textile industry is characterized by global mass production and has an immense impact on the environment. One garment can travel around the world through an extensive value chain before reaching its final consumption destination. The consumer receives little information about how the item was produced due to a lack of policy regulation. In this article, we explore understandings of ‘local clothing’ and how the concept could be an alternative to the current clothing industry. The analysis is based on fifteen interviews with eighteen informants from Western Norway as part of the research project KRUS about Norwegian wool. Five ways of understanding local clothing were identified from the interviews: production, place-specific garments, local clothing habits, home-based production and local circulation. We lack a language with which to describe local clothing that covers local forms of production as an alternative to current clothing production. As such, the article highlights an important obstacle to reorganization: local clothing needs a vocabulary among the public, in politics and in the public sector in general, with which to describe the diverse production processes behind clothing and textiles and their material properties.

Textile Cleaning and Odour Removal

Kirsi Laitala, Ingun Grimstad Klepp & Vilde Haugrønning

Consumers’ textile care practices today are characterized by frequent laundering. The importance of the removal of odours has increased, especially the smell of sweat. This chapter summarizes knowledge about removing odour from textiles. It provides information on suitable cleaning methods for different textile fibres and types of soils. The considered cleaning methods include laundering, stain removal, airing, hand wash, and professional cleaning methods. The cleaning result from laundering depends on water, washing temperature, length of washing cycle, types and amounts of laundry chemicals, and mechanical agitation applied. Textile material and type of soil that needs removal will determine the right mix of these factors.

Inherent fibre properties affect the soiling characteristics of garments. Comparisons of odours retained in textiles have shown that wool has the least intensive odour, followed by cotton, and synthetic polyester and polyamide garments have the most intense odour. Most textiles can be washed with water and detergents, which are more efficient in the removal of many odorous soils than dry-cleaning, but low-temperature laundering and/or lack of chemical disinfectants such as bleaches can contribute to odour build-up in textiles and in the washing machine. These aspects contribute to the environmental impacts of textiles.

Product lifetime in European and Norwegian policies

Nina Heidenstrøm, Pål Strandbakken, Vilde Haugrønning and Kirsi Laitala

Abstract

The objective in this report is to better understand how the increased product lifetime option has been positioned in policies over
the past twenty years. By means of policy document analysis, we explore product lifetime positioning in the EU’s circular economy
policies, Norwegian political party programs and official documents, environmental NGO documents, consumer organisation policies
and product policies. Overall, we find little focus on product lifetime between 2000-2015, however, there has been a massive
increase over the past five years. There is still a long way to go in developing appropriate policy instruments to address product
lifetime.

WOOLUME: Mapping the market for acoustic and sound absorbing products made of wool

Anna Schytte Sigaard and Vilde Haugrønning

Abstract

This report is the first deliverable from work package 2 of the WOOLUME project. The main goal of WOOLUME is to
explore different ways of using wool from Polish Mountain Sheep to achieve better utilisation of resources and value
creation. The aim of the report has been to map the market for acoustic and sound absorbing products made of wool to
examine the potential to introduce coarse wool as a material. This has been done through desktop research and
interviews with a focus on the qualities of wool as a natural product. Findings show that though man-made materials
dominate the market for acoustic products due to lower prices, wool is preferred as a material due to its natural
properties as well as aesthetics. Producers using wool consider their products to be high-end, intended for people who
want very good quality products and who are willing to pay a higher price to achieve this. However, few producers use
coarse wool in these products, and many are made of pure Merino wool. Using Merino wool which is often considered
of very fine quality due to the low micron-count does not correspond with the ideal of good utilisation of resources.
Therefore, we are proposing to utilise coarse wool which today is discarded as a mere by-product to meat-production.
Merino could instead be used for products where fineness and softness are important factors such as for clothing. In
addition, we argue for the rawness and uniqueness of the look of coarse wool as positive in terms of aesthetics and as
something that adds to the position of acoustic products made of wool as high-end.

Durable or cheap? Parents’ acquisition of children’s clothing

Ingun Grimstad Klepp & Vilde Haugrønning

Abstract

Parents are faced with a plurality of choices and concerns when it comes to the acquisition of clothing for their children. This paper explores how parents employ longevity in consumption of children’s clothing from a practice-oriented perspective. The material consists of 6 focus groups with 40 parents who have at least one child under the age of 18. The aim of the groups was to establish children’s clothing needs: how many they need of each garment, how long parents expect the garment to last and what they understand as quality in clothing.

The analysis shows that parents mainly opt for an ‘one or the other’ strategy; they choose what they understand as quality, often affiliated with specific brands, and accept paying more for the garment, or they mainly choose based on low prices, and expect less of the garment. Quality is evaluated based on the garments’ durability and function. More specifically, the parents measure the service lifetime of a garment based on the number of seasons it lasts, either in terms of wear and tear or the child growing out of it. The expected lifetime is defined by uncertain sources, from their own and friends’ experiences, and their desire to justify their own choices as well as routinised practices.

Our discussion section employs these findings and contextualise them within product lifetime discourses. By doing this, we provide knowledge about how quality is understood, and how brand and price are used as indicators. We show how lack of information about products, especially on garments, leads to uninformed consumption practices that have consequences for how quality and longevity are prioritised and understood.

Consumer practices for extending the social lifetimes of sofas and clothing

Vilde Haugrønning, Kirsi Laitala & Ingun Grimstad Klepp

Abstract

Consumers play an essential role in efforts to extend product lifetimes (PL) and consumers’ practices can determine how long and active lives products get. Applying the framework of Social Practice Theory, this paper argues that in order to suggest changes to how consumers can contribute to longer product lifespans, research needs to focus on consumer practices. The data material consists of 4 focus group interviews with 38 participants about household goods and 29 semi-structured interviews about clothing.

Previous research shows that consumers’ expectations of product lifetime has decreased, while satisfaction with products is relatively high, which may indicate that product break down and/or replacement is more accepted. Therefore, we argue, it is necessary to focus on social lifespans. Our findings show that products such as clothing and sofas often go out of use or are disposed of before their physical lifespan ends, and it is more common to donate or sell old clothing and sofas than buying the products second hand. There are a number of routinised practices, such as disposal of functional items, that are considered normal, which leads to less reflexivity of seemingly unsustainable practices.

The material in products, or the expectation to the material, is highly influential for practices that can extend the social lifespan, such as maintenance. We conclude that by understanding practices as integrated and influenced by elements of the material, social and cultural, policy interventions may have a greater impact on the social lifespan of products.

Increasing repair of household appliances, mobile phones and clothing: Experiences from consumers and the repair industry

Kirsi Laitala, Ingun Grimstad Klepp, Vilde Haugrønning, Harald Throne-Holst & Pål Strandbakken

Abstract

Increasing product lifespans is one of the most effective environmental strategies and therefore repair is a part of the circular economy approach that aims to keep products and materials longer in use. This article explores drivers and barriers for repair from consumers’ and commercial repair actors view-points, in order to understand how the repair rates of household appliances, mobile phones and clothing could be increased.

The study is based on a consumer survey of 1196 respondents in Norway, and 15 qualitative interviews with actors in the commercial repair industry working with repairs of household consumer goods. A surprisingly high share of repairs was conducted by consumers themselves. The main barrier is the consistently low price of new products, and often of poor quality, which contributes to low profitability in repair work for businesses and low motivation from consumers. Furthermore, access to competent personnel is a major challenge for the repair industry, a need which is expected to increase in the coming years.

Both the industry and consumers agree that better quality of products is a starting point for increased product lifespans, and this will also increase the motivation and the number of profitable repairs. These results have political implications on how to promote longer product lifespans through repair such as increased utilization and knowledge of consumers’ complaint and warranty rights.

Wardrobe sizes and clothing lifespans

Ingun Grimstad Klepp, Kirsi Laitala and Vilde Haugrønning

Abstract

It is easy to assume that a large wardrobe is characterized by excessive clothing and high acquisition, with little use of each garment and thus a big environmental impact. However, it is also possible to think the opposite; that the large wardrobe is a result of clothes remaining in use for a long time, that disposal happens rarely, while acquisition can be normal or even low. Whatever the reason, in a large wardrobe it is more likely that clothes become old before the technical life expires. This is because many of the garments are seldom used. Small wardrobes are often presented as favourable for both people and the environment, and as part of an ecological-friendly lifestyle, but we know little about the interaction between wardrobe sizes, longevity and the environmental impact.

In this paper, we investigate this relationship based on survey material from five countries; China, Germany, Japan, UK and the USA. We find that consumers with large wardrobes use their clothes longer, but consumers with small wardrobes use their clothes more often before they are disposed. We conclude that a good utilization of resources is possible with both large and small wardrobes, but in different ways. As we work towards more sustainable clothing consumption, we need to approach consumers differently, in order to give constructive advice to all.
