The dress worn by late British singer Amy Winehouse during her final performance has sold at auction for more than $335,000.

Winehouse wore the green and black dress during a show in June 2011 in Belgrade, Serbia, one month before she died aged 27.

The dress was part of a larger catalogue of items from the singer's life that went under the hammer, including clothing items and accessories, exercise machines and her DVD collection.

Julien's Auctions, based in California, estimated the dress would sell for $US15,000-$US20,000 ($20,700-$27,600).

But the dress sold for more than 10 times the estimated amount, with the winning bidder forking out $US243,200 ($335,616).

More than 800 items were sold in the auction, fetching more than $US4 million ($5.4 million).

Some of the items that were auctioned off, including the dress, will be exhibited at London's Design Museum until April next year.

Among the other major items purchased was a love-heart-shaped purse worn by Winehouse during the 2007 Brit Awards.

The purse sold for $US204,800 ($282,624), 10 times greater than the estimated price.
