When Mary-Kate and Ashley Olsen stepped out for last night's Sotheby's celebration, they arrived wearing oversize blazers and flats. Their pieces were simple, slouchy, and could have been worn straight from the office. Only the designer duo knows how to accessorize — Ashley twisted an oversize mustard scarf around her neck and chose spindly chandelier earrings.

Meanwhile, Mary-Kate slipped into luxe velvet loafers from The Row and contrasted her satin clutch with an emerald beaded bracelet. Instantly, they were jazzed up and ready to go. It's a quick solution we plan on taking advantage of this Spring, especially when we've got an event straight after work.
