H&M has opened its doors to Italian designer Roberto Cavalli who will create a one-off collection for women and men for the Swedish retailer.

"Roberto Cavalli has created a world of his own, iconic and full of fantasy, when it comes to colours, prints, and style," said H&M head of design, Margareta van den Bosch.

"There is no place for shyness and no possibility of ending up with a mainstream wardrobe of everyday basics. The Roberto Cavalli collections represents an exuberant, successful lifestyle."

The 'Roberto Cavalli at H&M' collection will be available in approximately 200 selected H&M stores worldwide for a limited period starting from 8 November 2007. The line will consist of 20 pieces of men's wear and 25 pieces women's wear.

"As the first Italian designer in the history of H&M, I enthusiastically welcomed this invitation, proud to bring the lively and positive spirit of my work to a new audience, who will be able to see and interpret my style in an individual way," added Roberto Cavalli.

"I love freedom and challenges, breaking down barriers, experimenting in different directions. H&M is all this for me."

Cavalli has designed clothing for stars including Madonna, Beyoncé, Gwyneth Paltrow, Charlize Theron, Jennifer Lopez, Sharon Stone, Gong Li, Victoria Beckham and Lenny Kravitz.
