Looks like Cressida Bonas is still out to show Prince Harry what he's missing.

The 25-year-old attended the Art Antiques London Gala evening in support of Children in Crisis at Kensington Gardens wearing quite the revealing get-up. The blond Brit was sporting a backless black top, which showed off some major side boob, and a pair of silky black and cream wide leg pants.

The socialite and up-and-coming actress, had her hair styled in a voluminous Kate Middleton-esque blow out, which looked amazing. Cressy kept things simple in terms of makeup, with just a little bit of smoky black eyeliner, and accessorized her look with a black clutch and sparkly silver heels.

Also in attendance for the event were Princess Eugenie and her mother, Duchess of York, Sarah Ferguson.
