If there was such a thing as a fashion "ace," this would be it.

Tennis star Venus Williams stepped out for a little retail therapy with her mother in Madrid on Wednesday, showing off some major skin in the process.

The racquet champ flaunted her incredibly fit stems as she browsed an outdoor mall in a barely-there black and magenta minidress. And what outfit is complete without a celebrity's favorite accessories? Williams accented her look with a Hello Kitty–encased iPhone and her adorable pup.

Check out Venus' leggy look below. And how does she stack up in our celebrity battle of the legs? You decide!
