This is an IxD group project solving wardrobe & outfit troubles caused by fast fashion. Target users are fashion lovers with massive clothes who waste time matching outfits and forget unused garments. We conducted user interviews & persona research, analyzed direct closet apps and indirect e-commerce platforms via a personalization-communication quadrant matrix. The app supports photo clothing input, weather/scene AI outfit generation, community sharing and wardrobe management. We finished user flows, low-fidelity wireframes and high-fidelity prototypes to help users save time on matching and reduce clothing waste.
