Lydia is famed for her love of floaty floral frocks and sharp tailoring but she decided to switch things up for a blogger's event in the city and we've fallen head-over-heels for her new look.
The reality star proved that casual can be cool as she slipped into these distressed denim dungarees that featured oversized pockets and rips at the knees. Giving us oodles of wardrobe inspiration, she teamed the covetable one-piece with a simple v-shaped blouse and Kylie Jenner-esque strappy sandals - we love!
Now, we know that Lydia is a bit of a designer fashion obsessive, but you'd be a fool to think the getup cost her a bomb. After fans and followers asked her where she nabbed the retro dungarees, Lydia took to Instagram to reveal that they were from none other than New Look - and guess what? - they only set her back £29.99.
That's what we call a bargain.
One of her Insta-followers wrote, "Love this look! And high street too," while another said, "Love that you've teamed them with a blouse."
After whizzing around London's Oxford Street, Lydia joined pals Ashley James and Vogue Williams at the Eco Tools party where she donned a bloom-adorned Miss Selfridge number.
