Tennis' fashion queen

The changing styles of tennis star and fashion student, Serena Williams

Catwoman: Fashion-concsious Serena Wlliams is currently wowing US Open crowds in a black PVC catsuit

Indomitable Lioness: Serena swaps colours more often than racquets, from striking yellow to Cameroon green

Mix 'n' match: The simple black tops may look the same, but the skirts add a touch of flamboyance

Pretty in pink: Serena goes for more of a feminine look, on and off the court

Hair-raising: Serena ditched the Jason Lee-style pineapple cut for a more glamourous look

Mamma mia: No matter how many hairstyles Serena tries out, she'll never be able to compete with her mum
