Rachel Roy has enlisted Canadian model Jessica Stam to lend her cool-girl style to three pieces for Roy's Rachel Rachel Roy line, sold exclusively at Macy's. The capsule collection will feature a jean, a cardigan and a handbag. "Just finished my first design meeting with @Rachel_Roy. I'm doing a capsule collection with her for Macy's. So much fun sketching designs!" the blond beauty recently tweeted. The pieces will be unveiled during Fashion Week next September and hit Macy's stores in October.
