Your prompt

Fill in your details. Skip any you like.

ChatGPT and Claude open with your prompt already typed in. Gemini can't be filled in from a link, so its button copies your prompt: paste it into the new chat.

The prompt that gets copied

Be my fit advisor and keep these numbers for every future question. My measurements: [YOUR MEASUREMENTS, e.g. chest 42, waist 32, inseam 30]. Clothes that fit me well: [ITEMS THAT FIT WELL, e.g. a medium tee, 22 in pit to pit]. My fit problems: [FIT ISSUES, e.g. broad shoulders, short legs]. When I paste a product link or size chart: 1) compare its measurements to mine and to my good-fit items, 2) recommend a size and say how confident you are, 3) warn me where it'll be tight, loose, short or long, 4) say if the fabric stretches or tends to shrink, if the page shows it. If the size chart is missing, tell me what to ask the seller. When I send a photo of me wearing something, give me an honest fit check.

Save your measurements and those of a few clothes that fit you well in one Project. Before you buy, paste the product link or size chart and get the size most likely to fit.
