As the anticipation builds for the Sonia Rykiel pour H&M fashion show (taking place later today in Paris) some behind-the-scenes images from the ad campaign, starring Lara Stone and Caroline Trentini, have been revealed. Rykiel's new lingerie collection for the retailer goes on sale this week. Boasting 70 pieces from chiffon kimonos to delicate briefs, it will be available on Saturday 5th December in 1,500 H&M stores worldwide and will go on sale at the same time at Rykiel boutiques.

"I wanted to show that I am very proud of this collection," Sonia Rykiel's daughter, Nathalie, who is president and artistic director of the fashion house, told WWD. "I also wanted to entice women who love our brand, but who may be hesitant to visit our boutiques."
