Everywear is a speculative design project that confronts climate crisis by reimagining fashion through the lens of world-building. Set in a future where textile waste is impossible, the platform enforces a "Power of One" philosophy, permitting users to own only a single, definitive garment per category- one jacket, one shirt, one pair of pants. I developed a brand identity and cohesive user flow that guides consumers through the intentional creation of their lifelong wardrobe, from selecting a base silhouette to customizing color and design elements. By transforming the traditional shopping experience into a high-stakes digital process, Everywear replaces impulsive consumption, proving that when we are limited to a singular choice, the value of the object becomes absolute.
