You know what they say -- double the outfits, double the fun.
Serena Williams served up ultimate glam realness at the premiere of her eponymous documentary, "Serena." Clad in a shimmering gold gown with a low neck and a super high slit, the tennis champion looked downright stunning.

Even fashionable friend Anna Wintour approved:

But Williams showed off her ever-versatile style in a completely different look for the after party: a tight white crop top, what appear to be leather cropped pants and patterned pumps.

Williams is undoubtedly most known for her stellar tennis skills, but she's also emerged as a force in the fashion industry. That notion was more evident than ever at the premiere: The event drew guests like Wintour, editor of American Vogue, and iconic designer Vera Wang:

We're totally in love with her two looks from the evening -- and we don't mean that in tennis terms.
