Olivia - loved up with island beau Alex Bowen - proved that she has one of the best wardrobes in reality TV when she rocked up to the event in this snappy ensemble that boasted a crisp white shirt complete with an embellished collar, slouchy dungarees slashed at the knees and a very cosy looking faux fur jacket that kept off the October chill.
She knows exactly how to put an outfit together, this one! And can we take a sec to appreciate how well she pulls off those cool, Halloween-inspired bunny ears? We want!
But as Olivia posed up a storm for the paparazzi, she was joined by a trio of blood drenched ghouls (OK, OK, they were really actors) who tried (and failed - ha!) to steal the limelight away from her.
Anyway, back to her gorgeous look.
A girl after our own heart, bargain hunter Olivia took to Instagram to give us another dose of #OlivesOutfits and she revealed that she looked to none other than high-street hotspot Quiz Clothing for her whole entire outfit - coat and creepers included!
Back in September, the stunner stopped by Reveal HQ to announce a collaboration with the affordable fashion brand and she spilled the beans LIVE on our Facebook page.
But that isn't her only recent venture - oh no.
Before heading off to the event which drew in the likes of CBB's Chloe Goodman and Josie Gibson, Olivia lifted the lid on a collaboration with former TOWIE star and Hair Rehab London founder Lauren Pope.
Exciting times, right?
TOWIE's Chloe Lewis, James 'Arg' Argent and X Factor's Fleur East to name but a few celebs also had the wits scared out of them at the event - but it's safe to say Olivia totally stole the show, as she always does!
