It's not every day you see Halle Berry, Sharon Stone and Leonardo DiCaprio's girlfriend Bar Rafaeli in one room, but such is the power of Italian designer Roberto Cavalli, who this week presented his collection for H&M at a glamorous party in Rome.

The designer, famous for his revealing dresses favoured by Victoria Beckham, follows in the footsteps of Stella McCartney, Karl Lagerfeld, and Viktor & Rolf, all of whom have designed successful lines for the high street brand in the past.

Jessica Stam and Erin Wasson were among the supermodels parading the pieces, which included chiffon animal-print dresses and tuxedo style jackets and trousers.

Halle Berry, no stranger to a glamorous frock,  said, "Roberto Cavalli is one of my personal favourites... I think the collaboration with H&M is great because now all women can wear his designs."

Sharon Stone added, "The clothes look great and the ads are beautiful. Roberto Cavalli is a wonderful designer who knows how to make clothes which are both chic and sexy."

The collection will be in stores from 8 November
