Dakota Johnson led an all star guest list at the Venice Film Festival premiere of her latest film 'A Bigger Splash'. The star opted for an off the shoulder number with some eye catching embellishments. Co Star Tilda Swinton also flashed some shoulder in a pastel hued gown while Matthias Schoenaerts was sleek and suited. Ralph Fiennes also stars in the film, and brought a casual edge to his double-breasted look by leaving his collar unbuttoned. Elizabeth Banks also made an appearance, turning heads in a figure hugging Marchesa gown. Her floor length dress featured some floral details and was covered in stunning lace.
