And it was Monroe who was still the big star turn at the sale when her buyers bidded big for her most famous on-screen outfits.
The white dress, which famously blew up as the star stood over a subway grate in the 1955 film, was the biggest money-spinner with a sale of $4.6 million, but her red sequin number from Gentlemen Prefer Blondes sold for $1.2 million , while her saloon costume from River of No Return was snapped up for $510,000 .
Fellow late Hollywood legend Judy Garland was also a big draw - her blue cotton dress worn in The Wizard of Oz was sold for $910,000 .
Other big sales included Charlie Chaplin's bowler hat, Dame Elizabeth Taylor's riding outfit from National Velvet and Ingrid Bergman's Joan of Arc armour.
Saturday was the first of the auctions being held by Reynolds at Profiles in History.
