And we're in LOVE with the look.
Even though the bash drew the likes of Lauren Pope, MIC's Binky Felstead and Lindsay Lohan, it was Chloe that turned the most heads with her bold choice of lippie.
Because we're beauty magpies, we know that stylish Ms. Sims used Inglot's brand new Matte Lipstick in 436, £13 to dress up her lips for the night out at the super-cool W Hotel - just be sure to apply a couple of swipes after blotting, to yield full coverage.
Chloe eschewed the fancy dresses for a black and white band tee which she tucked into this winner of a yellow leather skirt complete with gilded buttons down the front. A patent biker jacket gave the ensemble a tough, PFW inspired edge.
Sadly, Chloe's shoes were far from weather appropriate and she took to Snapchat to vent her frustration over her rain drenched suede heels - boo!
Thankfully, she and co-star Danielle Armstrong managed to cheer themselves up by making a quick pitstop at nearby M&M world for some treats to keep them sweet on the car journey home.
