Both fashion creators and other users can easily style outfits on different models. With our core tech, we are building an active community of fashion creators (designers, stylists, influencers, bloggers, artists, casting directors, etc..) who produce original designs and engaging content around the published pieces.

Our team combines deep expertise in technology (AI Phds) and the fashion industry (Community builder). Our Virtual Dressing room is live with top retailers (such as Neiman Marcus) and has ~1M ARR.
