Will I have to explain to my daughter that her brother is gonna make more money doing the exact same job because he's a man? If they both played sports since they were three years old, they both worked just as hard, but because he's a boy, they're gonna give him more money? Like, how am I gonna explain that to her? In tennis we've had great pioneers that paved the way - including Venus [Williams], who fought so hard for Wimbledon to pay women the same prize money they pay men, and Billie Jean King, who is one of the main reasons Title IX exists.

When you travel so much, the best and most relaxing thing is to just sit on the couch and not move.

You can't underestimate anyone.

My goal in a couple of years is to try to build a successful fashion house like Armani or Versace. I want that more than anything.

In the locker rooms, I'm always suggesting, "You need Berlei." Because it's the best brand for women and for me.

My mom taught me how to sew when I was super young; I used to make clothes for my dolls. When I finally went to [fashion design] school [in 1999], I really took to pattern making. Everyone in class was good at something; I was the person, if you need help with your patterns, you come to me and I would help you out.

I always say if I play my best it's difficult to beat me
