The trio headed to a blogger party in the capital and each looked as eye-catching as always, co-ordinating with one another slightly by donning various items of leather clothing.
Lauren looked simple, yet sexy in a high waisted green skirt, which featured a thigh split, a cropped long sleeve top from Zara and a leather jacket draped over her shoulders.
She added a pair of open toe strappy heels and a statement necklace from New Look to complete the outfit, as well as styling her blonde hair extensions in soft waves.
BFF and mother-of-one, Chloe upped the ante for the evening and opted for an ultra racy ensemble.
She teamed some figure hugging black dungarees with a shiny black bodysuit and a shaggy white jacket.
The TOWIE star also adorned herself in gold jewellery and slipped on a pair of peep toe shoe boots.
Her long brown hair was slicked up into a striking high bun and added a dark purple lip.
Meanwhile, Chloe's younger brother and Essex co-star Charlie switched up his usual smart style and went for ripped black jeans, a long black T-shirt and a collarless leather jacket.
Is it just us or does he look like the missing member of X Factor's Rough Copy?!
Before the evening, Charlie admitted that he couldn't wait to see his sibling and Lauren, tweeting: "Looking forward to tonight with @Chloe_Sims #BigSisterLove and to see @LaurenPope #PermanentCliqueMember .."
The three reality TV regulars appeared to have a great time at the London-based bash, which was thrown by Lauren's close friend Vas J Morgan in honour of the London Collections: Men shows that took place this week.
Also at the party were pop stars Mutya Buena and Jamelia.
