The brunette fashionista looked ready for summer while posing up a storm on the red carpet at the event, which was held at the Old Truman Brewery near Brick Lane.
Proving her love for a high street buy, Lydia sported a floaty sheer white camisole with cut-out spaghetti strap detailing, costing £14 from River Island. You can buy her cami in a whole host of other colours too - the sunny yellow version would be perfect for showing off a sunkissed tan!
Adding a bit of 1950s-style chic to her ensemble, Lydia tucked her top into a high-waisted baby pink skirt which featured a below-the-knee hem, pleat detailing and a super-pretty floral print.
She kept her talons bare and toted a large dove grey handbag while elongating her limbs with a pair of patent toe cap courts.
And Lydia totally upped the ante with her choice of jewellery, making a statement with an oversized floral necklace, £20 from her own collection for Vintagestyler.co.uk.
Her brunette locks were swept back into a fuss-free low ponytail and she flaunted quite possibly the lengthiest lashes we've ever seen, plus shimmery coral eyeshadow, groomed brows and soft pink lippy.
Lydia was accompanied by her sister Georgia - who recently made her TOWIE debut - for the evening, and, of course, the pair made sure they hit the photobooth!
Taking to Instagram to show off their snaps, Lydia wrote: "Gotta love a photo booth moment @xgeorgiabrightx #Skin&Blister."
We can see the love for dainty camisoles and statement necklaces runs in the family!
