Held every summer in London, Wimbledon is the oldest and perhaps most prestigious tennis tournament.

One of Wimbledon’s most notable traditions is its strict dress code for participants. Players are only allowed to wear white clothing, except for a centimeter of color at specified places, such as the neckline or cuff sleeves. And don’t think you can get away with cream or off-white; they’re banned, too. Oh, and shoes? Also white. The only exception to the all-white rule is for women, who can wear undershorts in darker colors, provided they are no longer than the shorts or skirts.
