The former TOWIE star was spotted attending the Simon Gao autumn/winter 2014 show in the capital and dressed to impress in a glamorous black, off-the-shoulder jumpsuit from her own collection.
She also added an extra sexy touch by styling her long brown hair extensions into gorgeous tumbling curls and carried a tiny gold clutch.
No doubt the Essex native had a great time taking in the sights of LFW and admiring the latest pieces from designer Simon Gao, as she is a fashionista in her own right and runs her own boutique Bella Sorella.
And she has been proving her style credentials all week too by transforming her looks in London.
Earlier this week, Lydia stepped out in a chic white outfit with patterned trousers for the Storm Model Management party.
In contrast to her head-turning jumpsuit last night (18 February), the ex-reality TV star opted for a super-smart ensemble and slicked back hair.
She certainly knows how to stay on trend!
Also at the Simon Gao show yesterday was chart-topping rapper Tinie Tempah, who caught everyone's eye in a shiny bright red suit, which he wore with his statement thick-rimmed glasses and a bow-tie.
Well, he knows how to make an entrance!
The 'Frisky' hit maker hit the FROW with the likes of Marvin and Rochelle Humes and then headed to a magazine party in the capital afterwards.
Truly indulging in his passion for fashion this week, Tinie was pictured at the Burberry Prorsum show on Monday (17 February) too, where he was caught laughing and joking with pal Harry Styles.
