Carine Roitfeld (former Editor-In-Chief of Vogue Paris doncha know) threw the biggest party of PFW - calling it! - in celebration of her CR Fashion Book Issue #5 and it was major.

Held at The Peninsula hotel in Paris, the guest list was a virtual Who’s Who of fashion in attendance: all the Kardashians (giving v. good lace and one huge brooch) Cara (#plunging), Selena Gomez (diamonds for days), Joan Smalls, Rosie H-W, Gigi Hadid, Olivia Palermo, Karl Lagerfeld and ummm… Justin Bieber. 

According to E!, Kim got on stage with Kendall and Gigi to sing Happy Birthday to Carine (we would have parted with good money to see/hear that). Oh, and if you’re wondering why everyone was pretty much werkin' all black ensembles, that’ll be because the theme was 'Inspired by Carine' (this is the kind of thing you can do when you're a fashion icon).
