Why Do Tennis Players Have to Dress in White at Wimbledon? Wimbledon's dress code is one of the most famous
in sports. The rules are so strict that the referee can force players to change under threat of disqualification. It's believed that the rule stems from the 1800s by the All England Club, which hosts Wimbledon. The sight of sweaty patches on colored clothes was considered to be inappropriate, so wearing white clothing was adopted to avoid embarrassment. Wimbledon is the only Grand Slam tournament that's still played on a grass court. It's also the only one that schedules a day off on the middle Sunday of the tournament.
