The reality beauty showed us that tartan shouldn't be confined to the depths of our autumn/winter wardrobe and flaunted her toned pins in these navy skinnies which were toughened up with the addition of silver, asymmetric zips.
Gorgeous Jess showed off her style credentials and teamed the busy bottoms with a crisp white shirt which she left open at the top to give us a glimpse of her assets - cheeky!
The stunner glammed up the super-smart look and fed her feet into a fierce pair of cobalt blue strappy shoes a la Kylie Jenner. She rather expertly managed avoid an embarrassing wardrobe malfunction as she sashayed past the paps and into London's swanky Sanctum Hotel in her eye-catching, sky-high heels.
That's what we call skills, people.
As always, Jess' locks were blowdried to absolute perfection. The stunning brunette ditched the poker straight look she rocked at ITV HQ in the morning to promote her brand new book 'Sparkling Stilettos' and styled her highlighted locks into cascading Hollywood waves - beautiful!
The Essex babe smouldered under the flashbulbs at the event attended by pals Casey Batchelor and Nikki Grahame thanks to her sexy smokey eyes and Kim Kardashian-esque nude lip, courtesy of make-up aficionado Krystal Dawn.
Anyone else got MAJOR brow envy?
Jess' trusty Louis Vuitton bag provided a chic contrast to those AH-MAZING patterned trousers while a cuff and a chunky gold watch gave a large helping of sass to an otherwise clean cut ensemble.
Does she ever get it wrong?!
