Serena may have her own collection of nail polishes, but we think that Venus is the Williams sister with the most underrated style. Her hair has varied (from a misguided asymmetrical cut to long blonde braids) as has her wardrobe (we remember that racy corset and those horrifying nude shorts), but looking back only shows how much she has evolved as a stylish woman in her own right.

In honor of Venus's 31st birthday, we put together a gallery of some of her most memorable looks from the past ten years (both hits and misses), on the court and off. Ready, set, go!
