Have you ever seen her look so hot?
The reality star made a splash as she poured her curves into these fierce white co-ords which boasted a boob-flashing cropped top - HELLO, cleavage - and a pair of 70s-inspired flares that sat on her hip and drew attention to her teeny waist.
Can we also just take a moment to appreciate her golden glow? Seamless!
Jess - who joined former TOWIE star Nicole Bass and pal Lydia Lucy - teamed her show-stopping (and every slinky) two piece with a pair of nude pointed court heels and a silver choker necklace but it was her hair and make-up that really stole the show.
Earlier this week, Jess took a huge beauty risk and removed her trademark flowing hair extensions (gasp!) but we were surprised to see how gorgeous her natural locks looked!
Jess showed us that midi lengths can be glamorous as she posed for a series of Instagram snaps and flaunted her sassy new colour.
