The 'Boom Clap' singer entertained the crowds at the Birmingham NEC on Saturday (5 December) when she took to the stage at the Alcatel One Touch Fashion Theatre in association with Capital FM.
It was a pretty perfect guest for the fashion and beauty trade show given how Charli's made a major name for herself as a fashion inspiration over the past couple of years.
Charli collaborated with Boohoo earlier this year on a gorgeous range that dropped in October. "I had so much fun designing pieces for the Boohoo winter collection. I can't wait to get it out there and to wear it myself. It's sparkly cute and sexy. I hope everyone loves it!" she said at the time.
Boohoo had said: "We are thrilled to be collaborating with Charli XCX and to be the first fashion brand to work with her in this way. Our customers love her music and her style as such; she is a perfect fit for the brand. The synergy between Music and fashion grows stronger daily and at boohoo.com, we are excited to be able to help further bridge this gap and bring some amazing fashion to our customers at very affordable prices."
The Clothes Show is taking place at the NEC until Tuesday with a string of celebrities scheduled to attend including Billie Faiers, Chloe Lewis, Binky Felstead, Charlotte Crosby, Joey Essex and Jamie Laing.
