The TOWIE star, 30, made sure she turned heads when she wore a bright orange PVC skirt and a black leather crop top to the brand new opening of 9 Swallow Street in London's Mayfair.
Arriving at the posh venue with TOWIE co-star Chloe Sims, Lauren had her hair in a loose top knot and wore strappy black heels.
Dressing up at home, Lauren had tweeted: "PVC and leather...oh my! Couldn't resist another @asos midi n @RareLondon crop top #london #dinner #HairRehabLondon."
She also revealed she was mixing business with pleasure as she was DJing at the launch party.
Meanwhile, Chloe wore a House Of Tre Li 'Dope' t'shirt and tweeted that she was "rocking a retro pony tail".
She also revealed that her fringe is here to stay, saying: "That's that then... The bangs is here to stay, was debating till I couldn't see out of my fringe if I should grow it out or cut it? It's cut."
Wearing the tee as a dress, she flashed her thin pins which seemed to go on forever!
Former TOWIE star Mark Wright also attended the glitzy event, wearing a roll neck jumper and jeans from his own Littlewoods range.
Arriving with fiancée Michelle Keegan, the pair looked keen to cosy up inside rather than smile for waiting photographers.
Michelle had earlier filmed Jonathan Ross' chat show for the first time, where she guests with Gary Barlow, Simon Pegg and Dame Edna Everage.
