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.
