The gorgeous Essex favourite joined the likes of brother Mark Wright and soon-to-be sister-in-law Michelle Keegan at a star-studded party thrown by The Sun newspaper in London on Monday (2 March).
Reality star and singer Jess went for a demure, sophisticated look in a snow white shift dress and matching jacket, teamed with simple nude heels, showing less can definitely be more!
She finished her look with a snakeskin print-style clutch bag.
Jessica joined a slew of TOWIE stars including Ferne McCann, Lauren Pope and Vas J. Morgan at yesterday's event, held at Kelly Brook's venue Steam & Rye.
TOWIE is currently airing its 14th series on ITVBe on Wednesday and Sunday nights.
On the most recent episode, we saw Jess laughing off ex-boyfriend Ricky Rayment's claim that he could have her back if he wanted, saying she would never rekindle that relationship.
