Seriously, how cute?!
The reality star turned fashion designer made everyone stop and stare as she slipped into this ah-mazing, red and white polkadot dress by Peggy Hartanto which boasted an over-sized pussybow and a circle hemline that dew attention to her perfectly tanned pins.
Jess whirled and twirled in the cool 80s-inspired number before sashaying on into the venue, and she contrasted the bright and bold look with a pair of two-tone strappy sandals for an extra edge.
She may have switched things up style wise, but when it came to her hair and make-up Jess' signature vibes shone through!
The stunner - who has her very own fashion collection with Lipstick Boutique - sported a sleeker than sleek blow-dry, a mauve-toned lip a la Kylie Jenner and a killer contour to boot.
Jess joined star of hit show Breakfast At Tiffany's Pixie Lott, Made In Chelsea's Nicola Hughes and Britain's Got Talent judge Alesha Dixon at the Haymarket bash, but it's safe to say he nabbed the most glamorous award.
