In the current context, where environmental protection is a priority, the role of responsible fashion is fundamental. Inspired by the nineteenth-century practice of adapting clothing to every occasion, I designed a modular shirt to create a functional wardrobe with less waste. My creation aims to revolutionize the concept of fashion; Through a playful approach, this t-shirt not only encourages consumers to adopt more responsible practices but also pushes them to make conscious choices suited to different occasions, thus reducing the need for too many items and better adapting to contemporary life. This proposal demonstrates how everyone can contribute to a positive impact on the environment.
