Matthew Williamson is to be the subject of a new book.

'Matthew Williamson' will follow the British-born fashion designer's journey from his debut collection in 1997 up to his present day global success.

A host of big names are expected to contribute to the book on Williamson, who counts celebrities such as Keira Knightley, Kate Hudson and Gwyneth Paltrow among his fans.

Actress Sienna Miller, a close friend and Muse to the designer, will provide the foreword while a host of big names from the world of fashion will give contributions.

These include editor of US Vogue Anna Wintour, British Vogue editor Alexandra Shulman, fashion designers Zandra Rhodes and Sir Paul Smith and Joan Burstein, founder of Browns boutique in London.

Written by fashion historian Colin McDowell the book will be lavishly decorated in Williamson's trademark vibrant colours and patterns.

Released in October, the tome will be accompanied by an exhibition at Somerset House in central London, which will run until January 2011.

The exhibition will launch with a party on October 12 where the central courtyard of Somerset House will be made over in a Matthew Williamson theme.
