Olivia Palermo Wore the One Piece Your Party Outfit Is Missing

Quick: You get a last-minute invite to an amazing dinner party—what's the very first thing you reach for in your closet? Most of us would rely on our go-to LBD, but Olivia Palermo just showed off a cooler choice that's a bit unexpected: a blazer with unique feather-fringe detailing.

While attending a dinner in New York City hosted by Williams Sonoma and Kate Spade New York, Palermo opted for the latter's Valerie Blazer ($1298) and Monster Leather Shoulder Bag ($378). While you might associate blazers with office attire, the feather detail took it to the next level and made it more festive for an after-dark fête. (Her quirky statement bag didn't hurt either.) Palermo rounded out the look with simple separates, including a white blouse, skinny jeans, and black ankle boots. As we've come to expect from Palermo, the result was a pitch-perfect look.
