I built FORMA to make clothing size guides easier to use while shopping online. It's a free Chrome extension that compares available garment information with your fit preferences and explains a possible size choice right beside the product. The workflow is simple: describe how you like clothes to fit, add measurements if you know them, enable shop access, and browse. FORMA can automatically assess recognised clothing pages, compare sizes and show where the evidence is missing. You can save pieces that fit and record the size you actually wore, so later comparisons have useful personal examples. The tricky part has been inconsistent size guides: flat widths versus circumferences, conversion tables pretending to be measurements, and missing sleeve information. I want the explanation to make those limits visible instead of presenting every recommendation as certain. It is an estimate, not a virtual try-on or a guarantee.

You can use your own Anthropic key, local Ollama, or No AI comparison with reliable measurements. FORMA is free; optional Anthropic calls cost extra and send relevant profile/fit information and product evidence to the provider. I'd appreciate feedback on the product itself: is the explanation enough to help you decide between two sizes, and which shop or garment type should I improve next?   submitted by   /u/moritzlauper [link]   [comments]
