About the challenge
Fashion is visual and personal, yet shopping for it online is still guesswork. Shoppers can't tell how a piece will look on them. Brands absorb the cost of returns. Good styling advice is hard to find.
HackTheFashion Global'26 is an online hackathon where builders from anywhere in the world fix that with AI. You'll build working products on [YOUR TRY-ON API NAME], a virtual try-on API that takes a photo of a person and a photo of a garment and returns a realistic image of that person wearing it. Build the shopping, styling or sustainability experience you wish existed. It can be a brand-new app or a serious upgrade to something you've already started.
Pick the track that fits your idea:
- Try-On Commerce. Make buying clothes online feel as confident as trying them on in a store. Think product-page try-on, shoppable lookbooks, and fit and size guidance that cuts returns.
- Styling & Wardrobe. Build the stylist everyone wishes they had. Ideas include agentic outfit planners, capsule wardrobes, and "wear what you already own" tools.
- Fashion for Everyone. Build for people fashion often overlooks, or for a better planet. Ideas include inclusive sizing, adaptive clothing, and resale and rental.
Ideas that don't fit neatly are welcome. Choose the closest track and tell us why in your description.
