Reality stars Danielle Armstrong, Jess Wright and Billie Faiers also stepped out at the much anticipated bash but as always, it was Lydia who gave us the most wardrobe envy in this ultra-pretty embroidered number, that boasted a crochet-trim hem, an opulent baroque print and 90s-esque spaghetti straps.
We were about to write Lydia's lovely look off as designer (sigh) but that's when it clicked, and we remembered that we'd seen it somewhere before...
Where, we hear you cry! Celebrity favourite AX Paris, of course!
Yep, that's right. Lydia's gorge party look can be yours with a click of a mouse and for an affordable £40, no less!
As not to detract from the eye-popping dress, Lydia popped on a simple pair of round-toe heels and a co-ordinating slouchy clutch bag.
The stunner - who wore her locks in super-sweet tousles - sipped away on cocktails and celebrated Ferne's new venture until the early hours.
Now if you'll excuse us, we have a virtual shopping basket to fill.
