The "Code Prototype" is a modular jacket. We deconstruct the jacket into three main parts: Collar, Sleeve and Body. Users can recombine the jacket form and functions by different parts, just like gears. Modular constructions are easier to fix or just changes the damages part. The users don't have to dump the whole jacket just because of small damage. We also hope this semi-customized design can make deeper connections between the products and human. Not just follow the “Fast Fashion”. We want to make fashion design more environmentally friendly and allow people to cherish their outfits.
