Even though professional athletes spend the majority of their time in uniform, it doesn't necessarily mean that they have no clue how to be stylish outside of the game. Actually, plenty of them are quite fashionable -- and some are so good at throwing an outfit together that they even have their own clothing lines.

Take Serena Williams, for example. While she certainly knows how to rock a tennis skirt, she doesn't look too shabby all dolled up in a slinky dress either! And when she's not on the court, she's putting her fashion design skills to the test with her label, Aneres.

And Serena isn't alone -- Take a look at the photos below to see eight other athletes who know a thing or two about putting together a winning look.

Who else do you think deserves credit for being a well-dressed athlete?
