The reality star - who joined Topshop clad BFF Courtney Green at the city bash - proved that it's OK to pare things back and she looked effortlessly stylish in a pair of khaki satin trousers and a sheer, slouchy shirt which offset her killer tan.
You can take the girl outta Essex...
Chloe channelled her inner Kylie Jenner and stood tall in a pair of co-ordinating khaki stripy sandals and like reality babe turned TV presenter Ferne McCann, jumped on the 90s bandwagon with a simple black choker.
As always, Chloe's Rapunzel-like tresses were the talk of the evening and she made like pal Court with tousled ends that trailed past her shoulders.
The star rubbed shoulders with the likes of Lauren Pope and a whole hoard of other fashion-savvy celebrity guests but her casual outfit is the one we'll definitely be copying!
