Amy Winehouse's Back To Black dress up for sale
The spotty strapless Disaya frock, complete with a bright red belt will be sold tomorrow evening at the Passion For Fashion auction in London, which opened for viewings this afternoon.
The proceeds will raise funds for the Amy Winehouse Foundation, a charity set up in the singer's memory.
Mitch said: "It's poignant, extremely poignant to me and sad in one way because obviously the dress shouldn't be here, Amy should be here.
"That is something I have to come to terms with and there are good days and there are bad days. Today is a good day because we're going to be raising money for the foundation.
Best-seller ... Amy Winehouse's Back To Black album
"It's going really well. We've made our first donations of 30,000.
"It's three lots of 10,000 to charities that really needed the money and we're hoping to donate at least half a million pounds in the first year."
In August it was revealed Back To Black had become the biggest-selling album in the UK in the 21st Century, with sales of 3.26million in the UK.
The dress, which will be sold by Kerry Taylor Auctions in central London, is expected to go for between 10,000 and 20,000.

Also included in the sale are items worn by Audrey Hepburn, Princess Diana and Elizabeth Taylor.
Mitch also said the Winehouse family will not release any more of the singer's unheard music unless it is "comparable" with her earlier hit records.
He said it was "a difficult decision" to decide to release a new album, which features outtakes, two completely new songs and a demo, in time for this Christmas.
He said: "The family view was nothing was going to go out unless it was comparable to (first album) Frank or Back To Black. If it wasn't as good as that then we wouldn't have allowed it to go out."
Mitch added sitting down to listen to the album, called Lioness: Hidden Treasures, was hard.
He said: "On one hand it was very difficult for us to listen to the album, on the other hand we had to do it to ensure the quality was as it should be."
Amy was found dead at her home in Camden, North London, on July 23 aged just 27.
An inquest heard that she was five times the legal limit drink drive limit when she died.
