We adore everything about this look!
The reality star - who recently lifted the lid on a collaboration with fashion hotspot Quiz Clothing LIVE on Reveal's Facebook page - looked nothing short of fabulous as she slipped into this stunning gothic-inspired playsuit that boasted a lace-adorned overlay, complete with floaty sleeves and a thigh-skimming shorts, and a nude slip to boot.
Never one to blend into the crowd, trendsetter Olivia - loved up with island beau Alex Bowen - swapped the dainty stilettos for a pair of chunky block heel sandals that snaked up her inked calves and she channelled her inner 90s chick with a matching choker and an understated nude lip.
But back to the one-piece! We've always known that Olivia is a true bargain hunter at heart, and while the rest of the celeb guests poured their curves into designer ensembles, Olivia looked to Quiz (duh!) for her look.
The best part, though? It won't bun a hole in your pocket at £29.99. One for party season, right? (Race you to the till!)
Olivia, famous for her tousled, bobbed lengths, went all sleek on us during the evening and slicked her hair back into a low ponytail that only served to accentuate her perfect contour and highlight combo.
The stunner - who appears totally starkers in this week's issue of Reveal to promote body confidence - hobnobbed with the likes of Vicky Pattison, Nikki Grahame and Tina Stinnes to name but a few stars who turned out to support Cally's latest fashion venture.
