Closet Mate is a three-tier mobile outfit recommendation app using React Native (Expo Go) on the client side, Python Flask REST API in the backend, and MySQL with external services for data and intelligence. The smartphone user interacts with four main screens—Login, Closet, Clothing Registration, and Outfit Recommendation—all communicating via REST endpoints (/auth, /clothes, /recommend, /feedback, /image). The Flask server integrates OpenWeather API for weather-aware suggestions and rembg library for automated background removal during clothing image uploads. This architecture demonstrates a scalable pattern for consumer mobile apps requiring real-time personalization, image processing, and third-party API orchestration.
