Jennifer Lawrence at the premiere of “Mother!” in New York. Jennifer Lawrence attended the New York premiere of her new film “Mother!” at Radio City Music Hall on Wednesday evening. Though the film, directed by her boyfriend, Darren Aronofsksy, is a psychological thriller whose trailers are filled with images of a grotesquely horrified Lawrence, the actress took on an entirely different aesthetic for the premiere. She stunned onlookers in a Dior couture gown. Its full tulle skirt and elegantly draped bodice made Lawrence look like a modern-day Cinderella. She pinned her hair in an elegant updo with flowers to match the film’s poster.

Lawrence kept the updo but changed her dress for the after-party following the premiere. Made by Ralph and Russo, this dress’s “wow” factor came from its sparkly finish and thick, vertical stripes, which fell to the floor while the rest of the dress stopped before Lawrence’s knees. Unlike the Dior gown, this dress kept her shoes visible.

Lawrence wore Casadei Techno Blade sandals, defined by a combination of a peep-toe and linear T-strap that allow a feminine appeal. Finished in a metallic glossy leather, the sandal is refined yet elegant.
