Called Olsenboye, the mid-priced juniors' line will feature various collections, each of which will highlight a different city of interest to the twins. The merchandise will include denim, bottoms, tops, dresses, skirts, shorts, jackets, handbags and shoes. The line will retail from $20 to $50 and is being designed to be mixed to create different looks. The items will be available in sizes 0 to 15.

"It's really important that Olsenboye serves lots of girls," Liz Sweney, Penney's executive vice president and general merchandise manager, said. "It's not just about girls size zero or one."
