The most valuable item of personal clothing ever owned is about to hit the auction block -- again.

The beige, rhinestone-encrusted dress Marilyn Monroe wore to sing "Happy Birthday" to President John F. Kennedy is being sold by Julien's Auctions in Los Angeles on November 17.

Created by Hollywood costume designer Jean Louis, the dress sold for $1.27 million at a Christie's auction in 1999, making it the most expensive personal item of clothing ever to be sold at auction.

It's estimated to sell for up to $3 million this time around.

"(How much it will sell for) is a difficult thing to predict, but we feel it will sell for more than double of its current estimate," said Darren Julien, president and CEO of Julien's Auctions. "It's truly the most important artifact of Marilyn's career that could ever be sold.
