Jay-Z recently appeared in a short film by Cass Bird where he gave a behind-the-scenes look at the Barclays Center, which was still under construction at the time. T Magazine released the video a few days ago and, as you can see, Hov was dressed to impress. Peep his Givenchy Striped Cotton-Jersey Sweater ($560) from the fall/winter 2012 collection. The sweater is currently sold out, so it'll be hard to get your hands on one.
