It's not every day that we see Mary-Kate and Ashley Olsen out, so it was a nice treat when the fashionable sisters showed up to an event in NYC last night. Ashley wore a white halter The Row dress with rosette detail cascading down the front, while Mary-Kate opted for a silky black dress also by The Row. But it was their fashion-forward accessories that really made their looks. We especially love Ashley's gold bracelets and antique rings and Mary-Kate's The Row crocodile bag and funky wedges. Zoom in on their accessories to draw inspiration, and then shop similar pieces to add pizzazz to your dress collection.
