At this point, you're probably used to seeing all-white outfits during Wimbledon, the long-running Grand Slam event held annually at the All England Lawn Tennis Club. But you might not know the origins of the monochrome look—or the severity with which the rule is enforced.
As to the latter, players are required to wear tennis attire that is "almost entirely white"—not off white or cream—as well as "almost entirely white shoes," including soles and laces, per the Wimbledon website. A single trim of color is allowed around a shirt neckline or around the cuff of the sleeves, but it can be no wider than one centimeter; the same goes for bottoms, which can have a similarly-sized colored strip along the outside seam.
