Michelle Williams looks wondrous in white at the pre-screening cocktail party for the premiere of My Week With Marilyn held at the Hudson Hotel on Sunday (October 9) in New York City.

The 31-year-old actress, who wore head-to-toe Dior to the New York Film Festival screening, was joined at the event by her Brokeback Mountain co-star Jake Gyllenhaal. Guests sipped Grey Goose at the cocktail party, before heading over to the premiere at Lincoln Center.

Michelle has garnered wonderful reviews for her portrayal of Marilyn Monroe.

“Michelle Williams gives a layered performance that goes beyond impersonation. Playing both the damaged, insecure woman and the sensual celebrity construct, Williams gets us on intimate terms with one of Hollywood’s most enduring and tragic icons,” wrote one reviewer for THR.
