If wearing a dress is more your style, go for a tennis costume. I love Venus Williams's style.
The costume basics entail:
- Tennis dress by Eleven, her line of tennis wear
- White visor
- Wilson tennis racket
- Accessory: Big silver plate for winning Wimbledon
If you would rather sport a Nike tennis dress, you could go as Serena Williams or Maria Sharapova, since they are both sponsored by the swoosh.
