"When fame happens," Katie Holmes has said, "a lot of people think you're changing.” Well, who can blame them? In just a few short years, the 31-year-old went from girl-next-door Joey Potter to Hollywood superstar mom. She even chopped off her signature long locks in favor of a Suri-friendly angled bob. Still, even with an ever-changing mane, she hasn't altered her pretty, polished style.
