Overview

• The king has changed the Windsor Court rule so that tennis whites are now preferred but not required for royals, staff and guests.
• The original all-white policy was introduced in 1919 and mirrored Wimbledon’s effort to mask sweat stains.
• Officials say the update aims to make matches more relaxed and reduce protocol restrictions on participants.
• This adjustment builds on Charles’s prior sustainability-driven move to cool the palace’s heated swimming pool.
• The Windsor Court has hosted royal players and charity events, including famed matches with Björn Borg and John McEnroe.
