The iconic white dress Monroe wore in The Seven Year Itch was a big seller at a Reynolds' Profiles in History event earlier this year (11) when it shattered records for a film costume sold at auction, and now more of the actress' costumes are to be sold.
The second part of the auction will feature four Monroe gowns from Gentlemen Prefer Blondes, Bus Stop, Niagara and Let's Make Love.
The items include a aubergine grey evening dress and Bolero jacket, designed by William Travilla, which the actress wore in Gentlemen Prefer Blondes. The two-piece outfit is expected to fetch upwards of $150,000 (£93,750).
A second Travilla dress, which the actress wore for her performance of That Old Black Magic in Bus Stop, is expected to sell for between $200,000 (£125,000) and $300,000 (£187,500).
Also going under the hammer are Monroe's Dorothy Jeakins dress from Niagara and the Jeakins strapless pale green pleated silk empire gown with a rhinestone trim the actress wore in for Let's Make Love.
The auction will be held at the Paley Center for Media in Beverly Hills, California on 3 December (11).
