Wimbledon first introduced its rule requiring clothing be "predominantly white" rule in 1963. Years later, in 1995, the All England Club changed it to an "almost entirely in white" rule. Seven restrictions/suggestions were composed that year and players at Wimbledon are required to adhere to them or risk the wrath of the referee, who has ultimate discretion on the matter.
A quick look through pictures from last year reveals that some players are slipping through the cracks. Below is the list of the seven Wimbledon clothing rules and examples of players who flaunted them.
No solid mass of colouring
Little or no dark or bold colours
No fluorescent colours
Preference towards pastel colours
Preference for back of shirt to be totally white
Preference for shorts and skirts to be totally white
All other items of clothing including hats, socks and shoes to be almost entirely white.
