Your one-stop AI fashion companion that analyzes your closet, mixes and matches pieces you already own, and creates on-point outfits for any occasion—without the morning panic of 'I have nothing to wear!'
Built for the Gemini 3 Hackathon 2026 - Powered by Google's Gemini 3 AI
We've all been there: standing in front of a full closet, overwhelmed, and screaming "I have nothing to wear!"
Despite having dozens of clothing items, we:
- Waste 15-20 minutes every morning deciding what to wear
- Experience outfit anxiety and decision fatigue
- Underutilize 60% of our wardrobe
- Buy duplicate items we already own
- Contribute to fashion waste by not maximizing existing clothes

-
** Digitizes Your Closet** - Upload photos of your clothes, and Gemini 3 Flash analyzes each item (color, style, formality, season, pattern, material)
