Around 800 of late English singer Amy Winehouse's personal belongings went under the hammer in Beverly Hills on Nov. 6-7. The dress that the singer Winehouse wore during her final stage performance sold Sunday for $243,200 – 16 times its estimated value.

Winehouse wore the green and black bamboo print dress at a concert in Belgrade in 2011.

A month later, on July 23, she died from acute alcohol poisoning. She was 27. Her death was the culmination of a lengthy – and often very public – struggle with alcohol and drugs.

The dress was the highlight of an 800-item collection of personal effects, ranging from bras and DVDs to books and makeup that were sold by Winehouse's parents, Mitch and Janis.

The entire collection brought in $4 million, twice the original forecast, according to auction house Julien's, which managed the sale that ran from Saturday to Sunday.

"Of course, there are fans and museums and collectors all over the world that will want to own some of these items, care for them, show them at museums, keep her legacy and her memory alive and at the same time raise some money for the foundation," Martin Nolan of Julien's said ahead of the auction.

The proceeds will go to the Amy Winehouse Foundation, which supports vulnerable young adults struggling with addiction.

"All of these dresses represent Amy – fantastic musician, songwriter, but also a fashion icon," Nolan said.

Multi-Grammy-winning Winehouse, whose seminal and soulful 2006 album "Back to Black," is counted as a modern classic, often spoke of her personal experiences battling alcohol and drug addiction.

Another highlight of the sale was the heart-shaped handbag custom-made by Moschino that Winehouse used at the 2007 Brit Awards, which sold for $204,800.

Many of the other dresses she wore in performances sold for between $12,500 and $150,000.
