It’s September, which means a new collection of Olsen-approved tees are available to StyleMint members and a new behind-the-scenes video is up. At this rate, there are going to be more StyleMint promotional videos on the internet than there are You’re Invited to Mary Kate and Ashley’s _____ Party VHS’s in my parents’ basement. Seriously though, Mary Kate and Ashley obviously learned at a very young age that them on screen = something people want to watch. This new video (via The Cut) sees Mary Kate, Ashley and Sara Moonves (who worked at Vogue and then followed Sally Singer to T and is now apparently a freelance stylist) conceptualizing the September shoot and talking about how they’ve known each other since they were, “like, zero.” Enjoy!
