Mary-Kate and Ashley Olsen are fashion chameleons who change up their style on a daily basis, so it is no surprise to see that their summer 2011 collection for Olsenboye, their lower-priced line created exclusively for JCPenney, has a very different vibe than their other two labels, The Row and Elizabeth & James. This summer, it appears that Olsenboye is all about ease—there is a breezy white lace sun dress, a floral mini dress, a draped violet tank top, a black ruffled party dress, and a paisley sun dress, just to name a few of the pieces. The recurring theme among these pieces? You can slip into every piece, add a couple of key accessories, and run out the door.
