Elizabeth Olsen attended the premiere of her new film Martha Marcy May Marlene in an Erdem dress with a painterly red and violet flower print, while Rachel Weisz took the trend in a more graphic direction when she wore a strapless Jason Wu frock covered in black and white blossoms to the Toronto debut of The Deep Blue Sea.
