Designer Rachel Roy took comfortable dressing to whole new level when she walked the red carpet at last night's One Day premiere in a set of striped pajamas! "I have an eleven-year-old and I like to show her that it’s OK to take fashion risks and to have fun and tell a story with fashion," Roy told InStyle. "I tweeted this weekend that you can’t have style without confidence and I really do genuinely believe that. I also believe in balance. It was hard for me to find something to go with these shoes where I didn’t feel too dressed up and too done. So I thought, this is how I can wear these shoes by Mr. Blahnik!" Roy's pajamas are currently available for $138 at Bedhead.com. Tell us, what do you think of her playful premiere look?
