Cressida's sexy style makeover

Cressida Bonas has turned heads as she stepped out for a charity event in London.

Prince Harry’s ex showed off her slim figure in a backless jumpsuit while she attended the Art Antiques London Gala Evening in aid of Children in Crisis at Kensington Gardens overnight.

The 29-year-old was reportedly all smiles as she sipped champagne and chatted with other guests, showing no signs of those widely speculated breakup blues since splitting from Harry in April.

For Cressida – who is known for her bohemian sense of style – this outfit is a bit out of the ordinary considering her usual hippie dresses and dungarees.
