The oldest tennis tournament in the world and regarded as the most prestigious, Wimbledon has been going since 1877. Being the only major tennis tournament played on outdoor grass courts, Wimbledon's dress code seems a little incongruous. As far as famous sports dress codes go, wearing white for tennis goes back further than Wimbledon - it goes as far back as the 1800's. For men as well as women, the whiter the outfit, the better. And Wimbledon is no different - white is white and no off-white or cream (unless on strawberries) is allowed on the courts.
