Marc Jacobs found himself a new muse! Marc has decided on British model Daisy Lowe (DJ Mark Ronson’s ex and Gavin Rossdale’s daughter) for his Spring/Summer 2009 Marc by Marc Jacobs campaign. At just 19, she’s acquired a tough-as-nails style that’s earned her a reputation for being one of Britain’s trendiest girls about town.

Daisy’s no newbie to snagging great campaigns—she’s modeled for labels Agent Provocateur and French Connection—but nothing will put her face on the supermodel map quite like this gig with Marc! And for our part, we’re happy about her latest career move: given her healthy body image, we’re hoping that British beauty will help do away with the stick-thin norm.
