Tournaments, which can be quite slow, are also a good venue for putting costumes on display.
Over the years there’s been hundreds of poker pros who have donned elaborate costumes at the WSOP, EPT or WPT. Sometimes it’s just for fun, other times it’s because of a lost bet and other times it’s merely a player repping some product or company. In the early 2000s you could even argue that most poker pros had costumes by default. Just think about Chris Ferguson’s trademark black duster and cowboy hat, Phil Hellmuth’s black hockey jersey and even Scotty Nguyen’s signature white duds.
