Why Wimbledon has this kind of operation

Since Wimbledon's inception, the tournament has had a strict rule that the players' dress code must be white, meant to show respect for the British royal family.

In 2014, an even stricter dress code was issued, and players were given a copy of Wimbledon's "White Ten" dress code before the match, detailing the rules, including the requirement that underwear seen during the match must be white.

In the first round of Wimbledon in 2015, the Canadian beauty Bouchard was almost penalized for slipping out of her black lingerie harness during a return, also because of Wimbledon's strict rules.

Of course, there are players who challenge the dress code. For example, Federer, the Swiss king who has always regarded Wimbledon as his favorite, could not tolerate the strange dress code at Wimbledon.

During a return, Bouchard's black underwear harness slipped out slightly under her jersey. This upset referee Angerer, who called the tournament's referee committee to discuss whether Bouchard should be penalized for the dress code violation.
