She's so fancy! Charli XCX ups the glamour in a grey satin gown with a draped neckline at fashion launch party

She's never one to shy away from breaking the rules and taking a fashion risk.

But Charli XCX played it safe in a classic dress as she attended the Vivienne Westwood X The Cambridge Satchel Company collaboration party on Tuesday evening.

The 22-year-old singer ditched her trademark quirky style for a more polished, grown-up look as she celebrated the launch of the new It bag at One Horse Guards in London.

Charli's grey satin number boasted a draped neckline and a puffball hem, clinging to her hourglass curves in all the right places.

The Boom Clap hit-maker set off the look with a pair of gold peep-toe heels and wore her hair scraped back in a disheveled updo.

She upped the glamour with smoky eye make-up and a deep red lip, with barrettes clipping any stray locks off her face.

She joked during an interview with Vice: 'When it comes to festivals in particular, you just can’t stop. That’s the key to survival. You’ve just got to roll on through and have vodka for breakfast.'

Charli rubbed shoulders with a host of stars including Sophie Ellis-Bextor, 36, at the satchel bash.

The pregnant singer, who is expecting her fourth child with The Feeling bassist Richard Jones, looked classy as ever in simple black dress.
