Kerry O'Brien never could have anticipated that her career in public relations would lead her to become an underwear designer, but that's exactly what happened. The entrepreneur started out in corporate PR, quickly making her way up the ranks (she was a vice president at just 25 years old). However, when September 11 happened, she felt like she needed a change. She quit her job without a plan, but it wasn't long before she found her next passion: women's underwear.
