Mary-Kate, Ashley, and Elizabeth Olsen all stepped out for the Costume Institute Gala at the Metropolitan Museum of Art in NYC on Monday night. We rarely get to see all three gorgeous girls together, so this was definitely a treat! The Olsens posed for photos as they made their way down the red carpet; Mary-Kate and Ashley  wore matching dark hues, while younger sister Elizabeth opted for pale blue Miu Miu . It's been a busy few months for all three girls; designers Ashley and Mary-Kate have been hard at work on their dual fragrances for Sephora  — they talked up the scents, called Nirvana, in an adorable interview on The Ellen DeGeneres Show  recently — while Elizabeth is gearing up for the May 16 release of Godzilla, in which she has a starring role.
Where their personal lives are concerned, Elizabeth and Mary-Kate are also currently planning their weddings. Mary-Kate became engaged  to French banker Olivier Sarkozy in late February, while Elizabeth and boyfriend Boyd Holbrook  decided to make things official just a few weeks later. When asked if she and her sister would be having a joint wedding , Elizabeth told Marie Claire UK , "No, I just told her she gets to pick a date first!"
