The reality star oozed cool as she made her debut at DSTRKT nightclub in this curve-hugging playsuit that boasted cape detail and teeny tiny, thigh-skimming shorts.
Can we also just take a moment to appreciate her perfect pins? What a babe.
Rivalling EOTB star and guest Jemma Lucy in the plunging neckline stakes, a super-tanned Olivia - who nabbed her one-piece from Prodigal Fox FYI - had no qualms about showing off her cleavage, but you know what they say - if you've got it, flaunt it!
Olivia drew attention to her intricate inkings and ditched the sky-high stilettos for a pair of lace-up block heel sandals from online fashion hub, Lamoda, and she proved that she is the queen of accessories with a 'YEAH' emblazoned clutch bag.
As always, the stunner - loved up with Islander Alex Bowen - rocked her locks in dishevelled, mussed up waves and she offset the glam vibes with a dramatic pair of lashes and a coral lip to boot.
Liv - who denied "throwing shade" at Zara Holland after she was grilled by the Loose Women panelists on Thursday afternoon (18 August) - rubbed shoulders with Rachel Fenton, Cally Jane Beech and former TOWIE star Abi Clarke to name but a few celebs at the bash.
