Serena Williams definitely enjoys tennis, but it doesn’t prevent her from having a passion for designing.

“I’m an unbelievable designer. I don’t know how I know and just do these things,” she told ABC News. “I just start sketching and then I just know the colors and I always know the forecast. I know green and purple are going to be hot. I was born to be a designer. I worked hard to be a tennis player, I don’t work hard to be a designer.”

The famous tennis player has her own clothing line called Aneres, her first name spelled backward, that she plans to sell in boutiques in Miami and Los Angeles.

Williams, known for her skintight outfits, including a leather-looking “catsuit” she wore as a 17-year-old at the U.S. Open and a cleavage-revealing red gown with strips of sheer fabric exposed at the London premiere of Pierce Brosnan’s new film, “After the Sunset.”

She is now designing outfits that she’ll wear next year.

But, despite the enthusiasm about her “fashionable” hobby, tennis remains the number one priority for the 23-year-old. “I love tennis more than designing because it’s actually easier and I don’t get nearly as nervous. I’m so nervous when I’m designing,” said the athlete.
