Olivia Palermo—you know, the style icon dominating your Pinterest feed with her nonstop ultra chic street style looks—knows fashion. Obvi. As Banana Republic’s Global Style Ambassador, she’s doing the fashion world a favor and releasing a capsule collection designed exclusively with the clothing and accessories retailer this September. The good news doesn’t stop there. Palermo and Banana Republic are giving us a sneak peak of the collection by debuting the first look—a seriously gorgeous luxe-sheen dress worthy of the great OP. Oh, and P.S. It’s available online now.

The dress is a beautiful off-the-shoulder silhouette with feminine bell sleeves and a cinched waist balanced by masculine button detailing. Rendered in a rich cayenne hue, the dress retails for $148 online at bananarepublic.gap.com and in store at the SoHo Banana Republic store in New York City.

This is only the first look, and, well, we can’t wait for the launch of the Olivia Palermo x Banana Republic collaboration coming this September.
