Fashion: You could take Kate Moss home if you're feeling charitable

Some of the best fashion photographs anywhere are for sale, says Tamsin Blanchard, for a good cause, but for one day only.

It is not often that you get the chance to own your own Kate Moss. On Friday, the annual charity exhibition Fashion Exposures opens to the public, giving you a one-day opportunity to buy original prints by fashion photographers. One of the highlights is this fabulously natural shot of la Moss, taken by David Sims for Harper's Bazaar last year.

Each year, fashion photographers donate a print to be sold in aid of the industry's charity, Fashion Acts. Last year you could pick up a portrait of Ossie Clark by Barry Lategan, a larger-than-life Steven Meisel or a Patrick Demarchelier. This year's photographers include Jeanloup Sieff, Linda and her daughter Mary McCartney, Steven Klein, and Katerina Jebb. Followers of fashion pages will also be familiar with Sheridan Morley's shot of a sun-dappled model Tizer Bailey, as seen in the Independent on Sunday Review, Gavin Bond's girl on a swing, taken for Vogue Australia, Sandro Sodano's picture of Michelle Hicks and Honor Fraser for Visionaire's Fashion 2000 book, and Garth Meyer's images of Africa.

If you are interested in fashion or portrait photography, not only is this a rare opportunity to start or stock up a collection, it is also a chance to sport some stars of the future. Last year, Tim Walker's image sold for a snip at pounds 50. He had just finished a stint assisting Richard Avedon. Now he's shooting for British Vogue. You never know whose picture may turn out to be an investment - and you do not often see so many photographers' work under one roof.

If you are more than just a window shopper, you have the bonus of knowing that your money is going to a worthy cause. Fashion Acts' causes this year include Devon HIV and Aids, The Food Chain, a meals-on-wheels service for people living with HIV and Aids, and Infant Aid, which helps support children in Romania. Last year Fashion Exposures raised pounds 28,000. This year, they are aiming for pounds 30,000.

If you see a picture you really like but can't afford, don't be afraid to make an offer. The bad news is that the show is for one day only.

`Fashion Exposures', at the Royal Society of British Sculptors, Dora House, 108 Old Brompton Road, London SW7, Friday 14 November, noon-7pm.
