French fashion extraordinaire Sonia Rykiel’s highly anticipated lingerie collaboration with H&M debuts in stores this week. The one-off collection marks a first for the successful series of collaborations that the fashion giant has secured with high-profile fashion designers.

The 70-piece collection will be available starting on Saturday in 1,500 H&M stores worldwide and will go on sale at the same time at Sonia Rykiel boutiques — the first time a guest designer for H&M will do so. “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.”

Taking inspiration from the main Rykiel line, the lingerie pieces have been designed to convey a Parisian, feminine and playful image through coquettish lace, Fifties-style pink satin, crystals and flower appliqués, as well as striped microfiber for the sportier looks. “I wanted a sensual and feminine collection,” Rykiel said.

Rykiel included “Hollywood homewear” items like chiffon kimonos in black or pink, black velour pajamas and a one-sleeve dress that can double as eveningwear. Matching hair accessories and slippers have been added to complement the lingerie offering.

Prices will start at $12 for thongs, $30, for bras and $114.50 for homewear.

The collection will be showcased at a party at the Grand Palais in Paris tonight in an elaborate Alice in Wonderland–inspired concept which involves 2.5-meter-high rabbits and a 25- to 30-meter-high replica of the Eiffel Tower with models being carted out on floats.
