Cressida Bonas: Even More Stunning Since Her Split from Prince Harry?

Did she do it to show what her ex Prince Harry is missing? And has her look gotten bolder – and better – since her split?
Bonas, 25, who recently nabbed her first movie role, dazzled photographers as she attended the event, organized by her friend Princess Eugenie.
It was Eugenie, 24, who introduced her to Harry, 29, and the couple enjoyed nearly two years together. That relationship ended in April, enabling Bonas to concentrate on establishing herself in her dance and acting career, some friends have said.
When she was dating Harry, the young dance graduate was known for scrunchies in her hair, denim overalls and sneakers. They are all still in her closet, but her appearance at the party for charity Children in Crisis showed she is ready to dress up daringly, too.
Cressida, who a party guest told PEOPLE has "some spirit," certainly seems more relaxed. Veteran royals author Judy Wade says, "She has more freedom – that's what that outfit she was wearing the other night was saying.
"She has the makings of a big star, and Harry will eat his heart out," Wade adds.
