Mary-Kate and Ashley Olsen are launching a new affordable and chic fashion line called Olsenboye, which will be sold exclusively at JCPenney stores in starting in November. The twins already have two higher priced lines, The Row and Elizabeth and James which have been very successful. The sisters talked about the launch of the brand on Good Morning America – check out the video here. The Olsenboye collection will feature denim, bottoms, tops, dresses, skirts, shorts, jackets, handbags and shoes. The line will retail from $20 to $50. We can’t wait to see better images of the denim! Here’s a look at the promotional video for the brand below. What do you think – will this new venture be as sucessful for the Olsen twins as their other lines, or will it flop?
