The Doing It Now singer proved that she isn't afraid to stand out from the crowd and made waves in the traffic-stopping green number that boasted an eye-wateringly high thigh-split, hefty ruched sleeves and piqued shoulders.
So many 80s vibes, it's unreal!
Charli totally owned arrivals in the dress and overshadowed guests such as Rosie Huntington-Whiteley, pregnant Liv Tyler and even Paloma Faith who was sporting a fabulous new fringe.
The stunner showed off her absolutely gorgeous curves (oh hey body envy!) in the leggy outfit and she dialled up the sass factor in a pair of lace-up court heels.
When it came to her make-up, Charli went all out and expected nothing less...
She contrasted her emerald gown with a vibrant pillar box red lip and rimmed her eyes with lashings of glossy, jet black eye shadow. Can we just take a second to admire those power brows?
Charli channelled her inner Kim Kardashian with tight braids and she posed up an absolute storm for the bedazzled photographers.
It's official - we adore her.
