Inspired by SDG 12 (Responsible Consumption and Production), the project “Strings Attached” involves the creation of modifiable items of clothing. The possibility to alter them is intended to generate a deeper interaction with the clothes, which in turn leads to an emotional attachment. This is part of the strategy of “Emotionally Durable Design” formulated by Jonathan Chapman, in which longevity and durability are achieved via an emotional relationship to the object. The topic is reinforced with the design motif of the metamorphosis of a butterfly, visible in the colours and structures.
