Rowan Cheung built a GPT-6 Astra app for daily outfit picks

Rowan Cheung says he built an app with GPT-6 Astra that selects his outfit each morning using live weather, with himself as the model. He describes the setup as uploading full-body and face photos, adding height, sizes, fit notes, and preferred and refused colors, then pasting a master prompt and letting it build for 1 to 2 hours.
