6. Marilyn Monroe's Dress ($1.26 million)Go to The NEXT Page for More Pictures >>>In New York the sale of a dress that screen legend, Marilyn Monroe, wore when she breathlessly sang Happy Birthday to President Kennedy in 1962 broke records by fetching more than $1m at an auction. The flesh-coloured dress, so tight she had to be sewn into it, had been expected to attract the highest bid when it went under the hammer at the end of the first session of a two-day auction at Christie's of her personal belongings - and it did. It originally cost $12,000, and the final bid of $1,267,500 easily broke the previous record for a dress sale at an auction which had been the $225,000 paid for an ink blue, Princess Diana gown that was sold two years ago. The dress, which has become a part of 20th Century American history, was worn by the glamorous star just three months before she died as she serenaded to the young president who was later assassinated. It was sold to New York dealers, Gotta Have It! Collectibles. Company co-owner Robert Schargin said afterwards he thought it was worth $3m. "We really got the bargain of the century," he said.
