Internet shoppers could add the flamboyant swan dress worn by Icelandic singer Bjork (search) to their wardrobe, with the eccentric fashion piece to be auctioned for charity next month.

International aid agency Oxfam (search) said Thursday the quirky dress, which the unconventional Icelandic songstress wore to the 2001 Oscars ceremony, was among more than 150 celebrity fashion items to be auctioned on Internet auction site eBay in aid of the organization.

Bjork turned heads when she wore the white dress, which features a ruffled feather skirt, with an imitation swan's neck draped around her neck and the bird's head resting on her breast, as she graced the Oscar's (search) red carpet.

Other celebrity garments and accessories in the charity auction lot include a screenprint shirt donated by U.N. Secretary-General Kofi Annan (search), Yoko Ono's sunglasses, a pair of fashion designer Stella McCartney's thigh-high fake leather boots and a mo-ped helmet used by Britpop band Blur's Damon Albarn.

The auction is being organized, in conjunction with Oxfam, by an online fashion web site and an art magazine, who asked celebrities to donate belongings with a story behind them. The successful bidder of each of the pieces will get the item, as well as a copy of it's accompanying story.

"We wanted people to give things that were personal and had a story behind them because bidders will then know they are getting something particularly special to the person concerned and all in aid of a good cause," said Rose Marsh, a spokeswoman for Oxfam.

Marsh said she expected the swan dress to draw interest from collectors or "fashion types."

"It's the sort of thing that's kind of priceless."

"We don't know yet how much these items could raise but if people get involved in a bidding war over Bjork's dress then it could be quite a substantial amount.

Bidding for the items open online on Sept. 18 and closes Sept. 25, coinciding with London Fashion Week.

All money raised will assist Oxfam's general program of aid work, Marsh said.
