The reality TV star and DJ was at the launch of castmate Danni Park-Dempsey's new restaurant Hors D'Oeuvre South Woodford, where she was joined by TOWIE stars past and present.
Lauren swapped her usual statement dresses for a pale blue chiffon camisole top and a white leather-look midi skirt, accessorising with tan peeptoe heels and a matching clutch.
She even ditched her usual blow-dry perfection for a sleek low ponytail, courtesy of a clip-in from her own Hair Rehab London range. Her trademark tan was set off expertly by her white skirt.
Good news if you love Lauren's pleated skirt as much as we do, it's available from ASOS for £45
