So Ashley Olsen wasn’t the most surprising celebrity at Oscar de la Renta‘s spring show—that honor would go to Justin Timberlake or Nicki Minaj, neither of whom we can imagine rocking one of Oscar’s embroidered lace ballgowns—but as far as lady starlets go, Olsen wasn’t the most expected. As the designer sent out one gorgeous, frothy creation after another—embroidered silk, beaded jackets, feathered columns—we tried to imagine the petite Olsen peeking out from any one of the looks, until the off-the-shoulder pink dress emerged. The only other time we’d seen those sleeves this decade (outside of period films) was when Olsen rocked the hard-to-wear look on the Met Ball’s red carpet in May. So now we know, Oscar gets his inspiration where every other woman does: from the Olsens.
