A badge or filter showing which Gis meet International Brazilian Jiu-Jitsu Federation standards (specific sleeve lengths, 100% cotton, and solid white, blue, or black colors).

Allow users to filter by weight. Recommend 350–450 GSM for daily training and 550+ GSM for heavy-duty durability.

Include filters for "L" (Long/Tall) and "H" (Husky/Strong) sizes to accommodate different body types beyond standard dimensions. 2. Weave & Weight (GSM) Selector

Add a calculator that predicts how much a 100% cotton Gi will shrink (typically 2–3 cm) after the first few washes.

Standardize sizing charts (e.g., A0–A4 for BJJ, 100cm–200cm for Karate) and prioritize height as the primary metric.
