Mary-Kate and Ashley Olsen attended the gala premiere of the opera Le Comte Ory last night in New York. The two sisters arrived in matching sunglasses, but otherwise wore quite different ensembles. They were both wearing Yves Saint Laurent which included cute envelope clutches. Ashley wore a statement green stole over her calf length black dress. Meanwhile, Mary-Kate wore a long sleeveless coat over a dress. Click through to see more photos on the twins looking fabulous!
