Last night Christian Dior and the Weinstein Company hosted an exclusive preview at Milk Studios of the two day only exhibit 'Picturing Marilyn.' In celebration of the upcoming film My Week With Marilyn, the exhibit displays 62 rare, unseen photos of the late icon. Including several photos from "The Last Session" taken by Bert Stern, just a few weeks before Marilyn's mysterious death. It also included an unpublished shot of her in a black, backless Dior gown. To honor that shot, Dree Hemingway made an appearance in a replica of the gown worn by Marilyn during that last photo session in 1962. Hauntingly beautiful!

Notable attendees included Georgina Chapman, Dominic Cooper, Jessica Stam, Nanette Lepore, Coco Rocha, Francesco Carronzzini and Harvey Weinstein, who added, "Marilyn had an innocence, an intelligence and a sexuality. It’s like an alchemist’s dream.”

The exhibit is for two days only, so get to Milk Studios asap if you want to get a glimpse of the rare photos. Also, don't forget to check out My Week with Marilyn, in theaters on November 23rd.
