Jess flew straight to the top of the style pile as she swapped the plunging bodycon frocks and slinky dresses for this seriously pretty printed number which boasted cool bell sleeves, a cuffed neck and a thigh skimming hemline to boot.
The stunner proved that she has a body-to-die for in the look that nipped her in at the waist and drew attention to her seamless (and enviably bronzed) pins.
Just gorgeous, right?!
Like KUWTK beauty Khloe Kardashian, Jess jumped on the over-the-knee boot bandwagon and stood tall in this luxe, seal-grey ruched pair that featured a killer stiletto heel.
We expected nothing less...
Can we also just take a moment to lust after her fierce and fabulous locks? Jess went for a vintage-style blow-dry, fashioning her hair (which looks a little lighter than usual, ooh!) into a side fringe - and we're HA-UGE fans of the barrel curled ends.
A glossy nude lip, lashings of kohl eyeliner and a pair of urban-style gold hoop earrings was all she needed to stand apart from the other celebrity attendees including CBB's Megan McKenna, Desi Rascals' Jasmin Walia and Love Island's Cally Jane Beech.
Gah, we adore her.
