Carine Roitfeld always throws the most fabulous fashion party in Paris Fashion week - you might remember her ball last season to celebrate her MAC Cosmetics range where Kanye West, Kate Moss, Cara Delevingne and Karl Lagerfeld descended on the swanky historic Hôtel Salomon de Rothschild in Paree.
Last night was the CR Fashion Book Issue 2' - Carine Roitfeld Cocktail party at Hotel Shangri-La in Paris and all the FROW heavyweights were in attendance. Ms Jessica Chastain has been attending almost as many shows as veteran FROW-er Leigh Lezark in Paris this week, as she has been snapped with Karl Lagerfeld at Chanel, sat next to Naomi Watts at Louis Vuitton and walked across the Tuileries en route to Viktor & Rolf. So of course she was at the cocktail party, steering clear of her usual block brights in an elegant black sleeved, belted gown. How very Roitfeld of her.
Hollywood slarlets Amanda Seyfried and Jessica Alba were also at the party, seen chatting to Kanye West. But the biggest shocker of the night had to be Kate Moss who rocked up with Jamie Hince in nada but a sheer sequin catsuit and a tuxedo jacket. The 39-year-old left little to imagination in a barely there outfit - but HOW does she keep that derriere so pert?
Leigh Lezark looked oh-so Parisian in a back tuxedo with just a black bra underneath, while Miroslava Duma wore a red cape to the event. Model Joan Smalls did an Angelina in a black asymmetric gown with a thigh high slit, whereas Karolina Kurkova went for a risky halter dress showing off a lotta lotta cleavage.
The fash pack all joined at the Hotel Shangri-La in Paris to celebrate the launch of CR Fashion Book 2, which is supported by Mercendes-Benz. The latest book is themed around Carine Roitfeld's obsession, dance. Roitfeld explains: 'I have always been obsessed by dancers’ bodies and Russian ballets.'
