Building MIRROR: A Luxury AI Fashion Try-On App with Perfect Corp APIs

Building MIRROR: A Luxury AI Fashion Try-On App I built MIRROR for DeveloperWeek 2026, which is a luxury fashion e-commerce prototype that lets users virtually try on clothing, shoes, bags, and earrings using AI. Here's how it works and what I learned building it. View the repo here What Is MIRROR? MIRROR is a full-stack web app that combines a luxury-styled product browsing experience with AI-powered virtual try-on. A user can browse products, open a try-on modal, upload a photo of themselves, see an AI-generated preview of them wearing the item, and add it to their cart. All of this can be done in the same page flow. The app covers four product categories: clothing, shoes, bags, and earrings. Each category has its own AI endpoint and unique payload structure.
