LONDON – Fifty Shades Darker, the film, is expected to hit theaters in February 2017, but a new lingerie line designed to capture the spirit of the books’ heroine will hit stores in September.

Coco de Mer and Fifty Shades author E.L. James teamed up to create the Fifty Shades Darker collection, which they said was inspired by Anastasia’s growth in sexual confidence as she gradually takes the dominant role in her relationship with billionaire Christian Grey.

“Fifty Shades Darker documents Anastasia’s growth in self-worth, which has a knock-on effect on her relationship with Christian,” said Coco de Mer Managing Director Lucy Litwack. “She is now more in control. It’s as if the roles have been reversed.

“Ana starts to uncover her underlying sexual desires, becoming more liberated in and out of the bedroom,” Litwack continued. “Taking inspiration from the Seattle skyline and the pivotal masquerade ball [in the book], the collection focuses on empowering women while remaining feminine and sophisticated.”

James said inspiration works both ways.

“I took inspiration from Coco de Mer when I was writing the books and visited the boutique in Covent Garden as part of my research,” she said. “Fifty Shades Darker lingerie really captures Ana’s sexual awakening. It is luxurious, deeply provocative and elegantly erotic.”

Pieces in the collection will be priced from $20 for a G-string to $80 for a robe. Fifty Shades Darker lingerie will be available at the Coco de Mer boutique, House of Fraser, Hunkemoller, Lovehoney and Asos.
