Celebrity DJ and young socialite Peaches Geldof revealed a more mature approach to fashion this week, at a star-studded charity event in London.

The 20-year-old rock chick performed a live set at the Vogue Bulgari Party at the Saatchi Gallery last night (October 13th) sporting a sophisticated black dress and tidy, slicked back hairstyle.

Peaches, who recently changed her hair colour from brunette to strawberry blonde, stood out on the red carpet for the 125th Bulgari anniversary bash for all the right reasons, proving that she can dress up her usually grungy sense of style.

The event was also attended by a host of glamorous stars including Bond girl Olga Kurylenko and fashionista Sadie Frost.

Known for being experimental with her image, this latest change to Peaches' appearance may signal a move to a more classical, polished look.

As a model, Peaches has posed for lingerie and fragrance brand Agent Provocateur.
