Serena Williams has endured her fair share of body criticism, especially when she's compared to other tennis players, including her sister, Venus Williams. Serena says it took a long time for her to be comfortable with her curves, telling DuJour, "I wasn't always confident. I just started feeling comfortable with myself about six or seven years ago. That's why I tell people that even at 25 or 26, it's OK if you're feeling uncomfortable with yourself. I was too. It's normal. I love who I am, and I encourage other people to love and embrace who they are."
