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.

Making Clothing Last: A Design Approach for Reducing the Environmental Impacts

Kirsi Laitala, Casper Boks & Ingun Grimstad Klepp

Abstract

This article discusses the extent it is possible to delay clothing disposal through improved design, thus reducing negative environmental impacts. This has been done by including user centered design methods into more traditional quantitative consumer research to give new insights for design. Empirical data on reasons for disposal of 620 clothing items from 35 persons in 16 Norwegian households was collected. In total, 70 different disposal reasons were registered, which were combined into seven main categories.

Changes in garments as well as size and fit issues dominated, while functional, situational, taste, and fashion related reasons were less common. The article concludes with design solutions on four levels related to the important disposal reasons including product design (material and shape), service design, and systems design, but also shows that consumer behaviour is crucial. In addition, the combination of results obtained with various qualitative and quantitative methods proved to be suitable for giving rich data that can be used to drive design research forward.
