Overview
- At Wimbledon 2026 a string of accepted and blocked items made the divide clear: Naomi Osaka’s kimono‑inspired walk‑on was approved, Novak Djokovic wore a heritage blazer, Jannik Sinner’s Gucci duffel was publicly celebrated, and Matteo Berrettini had an off‑white jacket stopped by officials.
- The All England Club requires players to wear clothing that is “almost entirely white,” explicitly bans off‑white or cream, limits coloured trim to very narrow widths and covers small details such as cap underbills and shoe soles.
- Wimbledon works directly with about 25 to 30 manufacturers to pre‑clear garments and routinely vets on‑court kit so brands and players must get bespoke items approved before public use to avoid being blocked.
- A targeted rule change in 2022 allows women to wear darker undershorts no longer than their skirt or shorts to address comfort and menstrual concerns, but that narrow accommodation sits inside an otherwise inflexible policy.
- The practical effect is that players and designers are finding subtle ways to tell personal or heritage stories through cut, embroidery and accessories while sponsors face operational risk because tiny shade or trim differences can scuttle activations.
