Maybe designer Adam Selman is doing most of the heavy lifting, but Rihanna is totes involved in the whole process — she even sends Adam her own personal sketches!
Check out the clip (above) to see RiRi approve and veto pieces from her upcoming River Island A/W 2013 collection, learn what topstiching is, and practically have an orgasm over the collection.
Also, she's braless in a cropped gray sweatshirt and you can see her nips.
Hey, just saying.
Press PLAY now!!!
Oh, and P.S. The clothes will be available in stores September 12!
