When we heard Charli XCX of Fancy fame was in town, we jumped at the chance for her to take the ASOS outfit challenge, and the Iggy Azalea and Icona Pop collaborator was more than happy to oblige. If you can't get enough of Charli, you're in luck, as her single, Boom Clap is out this week, and it's perfect heatwave listening.

Styling: Jo Greasley
