Despite their fashionista statuses, Mary-Kate and Ashley Olsen’s friends helped them design their latest fashion range.

The 23-year-old twins - who already have two clothing lines, The Row and Elizabeth + James - recently launched their new junior range, Olsenboye, and wanted input from their peers.

Mary-Kate said, “We’ve been working with our friends who are our age and in art school.”

Ashley added, “They’ve helped out with the art on the web sites and doing the commercials and the videos.”

The line - which is aimed mainly at teenagers, with most price tags under $50 - is sold exclusively at JCPenney and the girls are thrilled to be working with them. Mary-Kate told People, “All the people at JCPenney have totally embraced all of our friends that have now participated in these projects and it’s a lot of young talent and I think it’s really exciting.”

Ashley also revealed she is looking forward to next season’s looks as she’s not a huge admirer of the over-exaggerated shoulder look: “I’m a fan of strong shoulders, but I think the extreme shoulder, to me - it takes a very special person to pull it off. And I’m kind of ready to move on from that.”
