The TOWIE star joined her best pal Vas J. Morgan at the launch party for Naomi's Fashion For Relief pop-up shop in Westfield, London.
While many opt for a fail-safe LBD for a night out, Lauren mixed things up by sporting a summery all-white number, complete with a form-fitting silhouette which hugged her svelte figure.
Her sophisticated frock also featured a low V-neckline along with cap sleeves, plus cut-outs and an embroidered pattern running up either side.
The reality star kept the rest of her look very simple, adding a boyfriend watch and a dainty silver bangle while opting for an autumnal metallic brown hue on her nails.
But she did amp things up slightly with her choice of footwear, sporting beige suede numbers with laces which tied around her ankles. If you fancy snapping up a pair too, they're available to buy from Aquazzura - but they'll set you back £415. Eeek!
To complete her look, Lauren - who owns a hair extensions brand, Hair Rehab London - styled her golden blonde locks in soft, tousled waves, making her blue eyes pop with shimmery bronze eyeshadow, dark brown kohl pencil and lashings of mascara. Get her look with Charlotte Tilbury Luxury Eye Palette in The Dolce Vita, £38 - it's Lauren's go-to smoky eyeshadow palette.
