The Celebrity Big Brother star was attending the Pia Michi and Onanch London catwalk show so it's only right she dressed to impress in a gorgeous floor-length purple gown from Pia Michi.
Casey's sultry look, glossy brunette hair and curve-skimming dress prompted one Twitter follower to comment: "UK Kim Kardashian?"
A flattered Casey replied: "Hahaha! Why thanks! I wished lol. @kimkardashian is a beaut."
Model Casey met up with several celebrities at last night's event including Michelle Heaton and Liz McClarnon, but it seems she was most struck by a group from the Barnardo's children's charity.
Barnardo's was the beneficiary charity partner for the glam event, which took place at the plush Mayfair Millennium Hotel.
Tweeting after the evening had ended, Casey said: "So lovely to meet the @barnardos girls tonight at the @Piamichi fashion event :) Id love to do some work with u guys."
