The blonde bombshell looked sensational as she snapped an Instagram selfie yesterday (27 July) before heading to a Grease-themed party held at a fairground in Kent, where she was joined by the rest of her ITV2 co-stars.
But instead of donning an off-the-shoulder black bodysuit, Lauren put her own fashionable spin on the movie theme!
The starlet opted for a high-waisted powder blue skirt complete with a floral mesh overlay, which flared over her svelte silhouette and fell just below the knee.
Adding a hint of va-va-voom to her ensemble, Lauren flashed her midriff in a little black bralet while flaunting a chunky statement necklace.
But the cutest part of her look had to be her white frilly socks which she teamed with a pair of dove grey stappy sandals. We love!
Her tumbling locks were styled in beachy waves and she completed her retro outfit with an oversized bow placed on the side of her head.
The party was filmed for the finale of TOWIE series 12, and Lauren was spotted enjoying some time on the carousel with pal Vas J. Morgan and new love interest Lewis Bloor.
Vas opted for a white tee and leather jacket combo, while Lewis kept things a touch more casual in a beige chunky cardigan teamed with slicked-back hair.
And judging by the smiles on Lauren and Lewis' faces, they're feeling very loved-up!
Viewers have seen the pair's romance develop on the series, and last week Lewis took Lauren on a romantic dinner date along the River Thames... which Vas later gatecrashed! Oops!
