SHE can carry anything from a charity tote from Superdrug worth £2.99 to a designer Balenciaga bag and sales will go through the roof.

Love her or loathe her, the style and selling power of Kate Moss cannot be disputed. Some even feel the supermodel is more influential than many of the top designers today.

Fashionistas are now eagerly awaiting the new range she has designed for Top Shop which will be rolled out across the retailer's 308 stores this spring.

And many more stars will be following in her footsteps this season. For it's now de rigueur, it seems, to have a famous face to launch your high street fashion collection.

Actress 32-year-old Drew Barrymore is also set to bring a bit of Hollywood to the high street. The Music & Lyrics star is modelling the new Gold collection by British designer of the year Giles Deacon for retail giant New Look which has its company headquarters based in Dorset.

The range features animal prints, embroidered skinny jeans, cotton mini dresses and a range of accessories including out-sized sunglasses and funky jewellery.

And last week the Queen of Pop launched her M for Madonna collection for the cheap and chic Swedish retail chain H&M. The clothing line includes shifts and kimono dresses, trench coats and accessories ranging in price from £7.99 to £150.

But some believe that our obsession with celebrity is finally reaching saturation point. Madonna's first attempt at fashion design - a white track suit and other sporty attire for the same store - had a lukewarm reception.

Sarah Charles, fashion course leader at the Arts Institute in Bournemouth, believes the consumer is getting jaded with the whole concept of celebrity-endorsed fashion.

"Ever since Audrey Hepburn in the 1950s there has been a strong link between fashion and celebrity but we may have reached saturation point when it comes to celebrity endorsement which is partly because of the over use of the term celebrity in the media.

"I think now it very much depends on the celebrity. Brands are more likely to succeed when the celebrity has been involved in the actual design of the clothing range as opposed to just modelling it.

"Elle Macpherson is a good example. She has huge success with her lingerie range but she has been very closely involved with the concept - it's not just her looking pretty in a bra designed by someone else."

Local fashion consultant for West Quay, Lucy Rosseter, thinks it adds a bit of glamour and interest to the high street.

"It could run out soon but I think there is still a lot of power in celebrity at the moment. Whether you like it or not, Kate Moss still has a lot of influence on young women so I think it's a very shrewd move by Top Shop.

"However I'm not sure that designer pieces always translate so well on the high street when it comes to quality of the clothing - but at least it gives people a chance to buy into a look or lifestyle that they would otherwise be unable to afford."

Kate Bussmann editor of In Style magazine said: "I think it brings in a new clientele - people are buying into the name of Madonna - they are buying a little bit of her cache."

But Grace Housego, marketing executive at Beales in Bournemouth, says celebrity endorsement is not a route that their store is ever likely to go down.

"I think our customers prefer good cut and quality rather than buying into a trend. We do stock designer ranges like Anne Klein but that's more to do with her integrity than her influence as a designer."
