A rare piece of memorabilia from Prince's 1984 classic film Purple Rain is going under the hammer.
The pop superstar, who died last week, wore the black and white blazer with leather sleeves while riding a motorcycle with co-star Apollonia Kotero.
"It's definitely the most important piece of screen-worn Prince clothing that's ever come up for auction," said Joe Maddalena, president of auction house Profiles In History, based in Calabasas, California.
"This is a signature piece of wardrobe worn from an iconic movie in his most famous role."
The coat is a unique find from the typically reclusive artist, the auctioneer said. He believes the Purple Rain blazer will be the "star of the show" and expects it to sell for much more than the asking price - 6,000 to 8,000 US dollars (£4,100 to £5,500).
"Prince memorabilia in general, it just really doesn't exist. It seems like he controlled it all," Maddalena added.
"This is the first time ever for something like this, and it might be the only time because the rest of the costumes may be in his (personal) wardrobe."
The original seller said her sister, a make-up artist, received the piece from Prince after they worked together on Purple Rain.
The auction on June 29 will also include costumes from Britney Spears, Katy Perry, Alicia Keys and a Swarovski crystal-studded glove from Michael Jackson's 1992 Dangerous world tour.
