"We are all baffled as to why some of her designer dresses didn't go too. There were a couple from Dolce & Gabbana worth a fortune ... Her wedding dress was only a little cotton thing, a hundred quid at best in the shops. Whoever nicked it realized its significance and knew it had an extra value," Mitch, 60, tells The Sun. "It's sickening that someone would steal something in the knowledge of its sentimental value."

The other stolen dress is the cocktail dress Amy wore to perform on the Jools Holland show later that year. Both pieces had been set aside for auction in New York to raise money for The Amy Winehouse Foundation, which benefits children's hospices and drug addiction counseling. The dresses were expected to bring in approximately $210,000.
