The 23-time grand slam champion was playing in her first major since giving birth to her first child in September. "I feel like a warrior princess in it," she told reporters. " I'm always living in a fantasy world. I always wanted to be a superhero, and it's kind of my way of being a superhero."
The 36-year-old American said the skintight suit also served a practical purpose after enduring a difficult childbirth. "I had a lot of problems with my blood clots. So there is definitely a little functionality to it," she said.
