They got the memo: Kim Kardashian, Cara Delevingne and Selena Gomez party in plunging black suits
Suits you, ladies.
The power suit is fast becoing the must-have red carpet look and Hollywood's most stylish certainly took note during Paris Fashion Week.
At last night's event for the launch of the fifth issue of former Vogue Paris editor Carine Roitfeld's new publishing venture, the CR Book, the most stylish woen in Tinseltown posed in similarly stylish attire.
PFW staple Kim Kardashian opted for a typically eye-catching black trousers, plunging top and embellished blazer, while actress Selena Gomez wore a racy black silk jumpsuit and super model Cara Delevingne left little to the imagination in her semi-sheer bodysuit with strategically covered panels.
The party attracted the hottest names in the industry as Fashion Month comes to a close, including Olivia Palermo, Rosie Huntington-Whiteley, Miranda Kerr, Justin Bieber, and Paris and Nicky HIlton.
Noticeably absent from the bash was model-of-the-moment Kendall Jenner, who reportedly enjoyed a dinner date with Bieber earlier in the night, and her momager Kris Jenner was sure to make an appearance.
Yesterday saw Chanel, Valentino and Paul & Joe show their Spring/Summer '15 collection to critical praise and star-studded front rows.
