Mary-Kate and Ashley Olsen are easily the most chic people who have ever walked the earth. Photograph by Stephen Lovekin / Via Getty Images for Mercedes-Benz Fashion Week Just looking at them makes you feel the ~*cool girl*~ vibes. They look like goddamn rock stars in every picture they take. Pascal Le Segretain / Via Getty Images Don't you just want to know what they're thinking about? But there's something you don't know about the twins. They have a ridiculously easy trick for looking chic in pictures. Neilson Barnard / Via Getty Images for JCPenney And the good news is that you, too, can use their trick. Just before they pose for the camera, the sisters turn to each other... Larry Busacca / Via Getty Images They ready themselves for the flashes... Advertisement And they whisper the word "prune." Cindy Ord / Via Getty Images Yes, really. The "PR" sound purses their lips just a little bit, while the "OON" sound relaxes their mouths. Dave Kotinsky / Via Getty Images for JCPenney And it works. Every. Damn. Time. Just look at Mary-Kate, thinking about imaginary prunes in the distance. Amy Sussman / Via Getty Images The poster child for chill. For comparison, here's what happens when Mary-Kate (right) is all about the prunes, but Ashley (left) forgets the code word and just smiles. Jason Kempin / Via Getty Images Don't even pretend Mary-Kate doesn't look more badass than her sister. Advertisement Everyone can get a little nervous when the camera comes out.
