The reality star is famous for putting a vintage twist on things and she served heaps of 20s vibes in this lovely nude gown that boasted a drape-style maxi skirt and a sequin-adorned bodice.
We can't take our eyes off of it!
Lydia looked like a Grecian goddess in the dress as she gave us a little glimpse of her cleavage, but it was her retro-inspired up-do, with gorgeously girly tendrils and a sweeping side fringe - that really grabbed our attention.
Is there a hairstyle she can't ace like a total pro?
Lydia - who showed off her subtle Marbella glow as she posed for the paparazzi - joined TOWIE co-stars Danielle Armstrong and Georgia Kousoulou at the event, not to mention Nicole Scherzinger and Michelle Keegan.
Just last month, Lydia and her mum Debbie announced some very exciting news - they're going to start presenting fashion on ITV's Lorraine this winter!
On Thursday evening, (27 October) a super excited Lydia took to Instagram to lift the lid on her latest venture and she captioned a selfie including lovely Debs, "So excited to announce me and mother hubs are presenting fashion for @itvlorraine this winter. On set today. #DreamJob #Fashion."
With that in mind, we've no doubt the style-savvy duo are going to serve up all the hottest trends we should be pouncing on this winter, and it seems we're not the only ones looking forward to it.
"Well done! This is such amazing news," wrote one Insta-user, while another commented, "Ah can't wait to see you! Both so lovely!"
Debbie also took to social media to give us a glimpse of what we can expect and she posted a number of cute clips of Lydia and herself emerging from a series of high-street shops laden with bags bursting with AW16 pieces.
We can't wait to watch!
