JOIN Collective Clothes is an ongoing design and research project that playfully questions the fashion system by exploring fashion as a collective practice. The fundament of the project is a modular clothing system that consists of four different shapes which can be combined into a full outfit (a sleeve, a top, a trouser leg and a part of a skirt). An easy-to-use open source manual, designed by Beau Bertens, invites people to get started in creating their own garment. Anyone can participate by choosing one of these shapes and making their own JOIN piece which can eventually be connected to a piece made by another maker. Regardless of location and experience, either working from home, or participating in one of the JOIN workshops, JOIN creates the possibility to come together, share ideas and experiment with form, texture, technique and material.
