Serena And Venus Williams On Cover Of Hamptons Magazine

The U.S. Open is only a few days away, but Venus and Serena Williams found the time to fete their Hamptons Magazine cover last night before the Grand Slam tournament begins next week.

In their issue of the magazine, the superstar sisters talk about starting their own tennis tournament and what you can expect them wearing at the Open.

"The US Open this year is all about the little black dress, and I always put zippers in my dresses, so there will be a zipper down the back. Because I don’t ever wear black in the daytime, it will be opposing colors. Last year there were three different styles; this year it will be simple because it is just one, but in different colors," says Venus.

As for Serena, perhaps she'll wear something inspired by her HSN collection and complete the look with "Serving Up Sparkle" the dazzling silver nail polish from her signature OPI collection.
