Eeep! We don't quite know where to look!
The reality star drew gasps as she rocked up to the event in a totally sheer, figure-hugging jumpsuit that boasted transparent sleeves, trousers and a swimsuit-style body to boot.
Marnie ditched her undies in the super-revealing one-piece and gave us all a very cheeky flash of her bare bottom while she posed up a storm for the photographers. Later on in the evening, however, the stunner left virtually nothing to the imagination as she was papped getting into a taxi.
Marnie teamed her traffic-stopping look with a a pair of strappy stiletto sandals which only served to accentuate her supermodel pins. She basked under the camera flashes and flaunted her incredible bronzed glow and lustrous lengths before joining the rest of the guests for drinks and a catch up.
Everyone from TOWIE's Danielle Armstrong, to Ex On The Beach's Megan McKenna looked sensationally glam at the star studded bash held at swanky Kensington Roof Gardens, but no-one turned as many heads as our Marnie - FACT.
