​Marilyn Monroe's love letters and BRA up for auction: 'Lost Archives' pieces expected to fetch more than $1million

As one of Hollywood's greatest sex symbols, she was known to have a turbulent private life.

Now, Marilyn Monroe's love letters - and bizarrely, one of her bras - are being put up for auction in Beverly Hills, California.

The letters, penned by the actress and her lovers, including playwright Arthur Miller and baseball great Joe DiMaggio, are among 300 items to go on sale as part of 'Marilyn Monroe's Lost Archives'.

They also feature the actress's white bra, a framed letter from costume designer Cecil Beaton, a Dior black silk dress and a fawn-colored silk overcoat with a black velvet collar.

With regard to the love letters, one written by DiMaggio when Monroe announced she was filing for divorce after a matter of months in 1954 reads: 'I love you and want to be with you'.

It continues: 'There is nothing I would like better than to restore your confidence in me.'

DiMaggio, a famously stoic and private man, was pictured crying at Monroe's funeral in 1962 and for the following two decades, had flowers placed at her crypt several times a week.

Another letter in the collection - which will go on sale at Julien's Auctions in Beverly Hills next month - is from Monroe to her third and final husband, Miller, in which she muses about her insecurities.

Others are from Monroe's friends, such as Clark Gable, Cary Grant and Jane Russell; with the latter imploring the actress in 10 handwritten pages to give her marriage to DiMaggio another chance.
