4 months after her death and the family of Amy Winehouse are coming to terms with how they are going to deal with Christmas without the star. They are still keeping themselves busy and have thrown themselves into raising money in Amy's name. Her dad Mitch has set up the Amy Winehouse Foundation to help other people that may be in a similar situation to Amy. There is an auction in London today and one of Amy's famous dresses goes on sale. It's the frock she wore on the cover of the album Back to Black. It's a spotty strapless dress with a red belt. Her dad 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." Mitch also talked about how it as all going. He said: "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." The dress is expected to make £10-20,000. It was revealed that after Amy's death, her album Back to Black had become the biggest-selling album in the UK in the 21st Century, with sales of 3.26million in the UK. As far as hearing any more music from Amy goes, Mitch has said they will release it Ð but only if it's good enough. He described it as a difficult decision to choose to release an album in time for this Christmas and said: "The family view was nothing was going to go out unless it was comparable to Frank or Back To Black. If it wasn't as good as that then we wouldn't have allowed it to go out." The album will be called Lioness: Hidden Treasures. It features outtakes, two completely new songs and a demo.
