The dress worn by Amy Winehouse on the front of her Back To Black album has sold for more than £40,000 at auction.

The polka dot chiffon dress was bought by a South American fashion museum, with the proceeds going to the foundation set up by the late singer’s family in her memory.

Ms Winehouse was found dead at her home in Camden, north London, this July after a lengthy – and public – battle with drink and drugs.

Her father Mitch was at the auction in central London to see the dress fetch £43,200 after the winning bid was made by the Museo de la Moda in Santiago, Chile.

He said: “We are just over the moon and we owe a great debt to the designer, Disaya, who donated the proceeds from the sale.”

The foundation has already made three donations – each of £10,000 – to separate children’s charities including a hospice and a project that helps seriously ill babies.

A new album of unreleased tracks, called Lioness: Hidden Treasures, is being released on Monday with £1 from each album sold going to the foundation.

Mr Winehouse said: “We are very proud to be helping these deserving causes and have been overwhelmed by the support the foundation has received.”
