Julien's Auctions will be hosting a sale of some of Monroe's belongings which includes the shimmering dress that Monroe wore to sing "Happy Birthday" to President John F. Kennedy at his 45th birthday celebration.

• The dress designed by Jean Louis was designed exclusively for Monroe.
• Original cost $12,000 in 1962.
• Sold in 1999 for over $1.26 million.
• More than half a century later, the auction house estimates that the dress is worth somewhere between $2 to $3 million.

The flesh-colored, sheer dress features over 2,500 rhinestones. It was said to be so tight fitting at the time, that Monroe had to be sewn into it on the day of the celebration. But besides the stunning design, it was the fact that Monroe wore absolutely nothing underneath the gown that left a lasting memory.
