Essex model Casey joined a host of stars on Wednesday night (10 December) at the KAZAM Tornado 348 smartphone launch party, which was held at Raffles nightclub.
Covering up, but still keeping it chic, Casey turned heads in a gorgeous oxblood top and skirt combo.
The round neck top, which is from Rare London, is priced at £32. The knee-length PU panel skirt, also from Rare, retails at £36.
Casey, who went under the knife in August to have her natural breasts reduced from a GG to a EE cup, completed her outfit with nude heels and a tan handbag.
The party was attended by the likes of former TOWIE star Lucy Mecklenburgh, Made In Chelsea's Cheska Hull, Capital FM DJ Greg Burns and N-Dubz star Tulisa, who also performed on stage.
Casey, who appeared on series 13 of CBB earlier this year with Tulisa's cousin Dappy, said: "Soooo lovely to see my gorge girl @officialtulisa you was amazing tonight! Great performance! Wish @TheDappy was here."
