How do you celebrate Halloween when you're hot, rich and insanely fit??
You suit up (or strip down) with a baller costume -- kinda like women's tennis star Genie Bouchard, whose Bae-watch look gave us prime Pam Anderson flashbacks.
Tons of other sports stars showed out too, including Steph Curry, Danica Patrick, Giancarlo Stanton, and Floyd Mayweather -- who had a trifecta of get-ups for his hallo-weekend parties.
Who wins the costume contest?
We do. Kick back with some candy and enjoy the pics.
