Rap mogul Jay-Z was recently spotted out in Miami with his wife Beyonce wearing a Balmain Crest Button Down shirt ($698) in blue from their Spring/Summer 2010 collection. The shirt features military style epaulets, two front chest pockets, and a Balmain crest below the left chest pocket. If you can remember, Balmain launched their first menswear collection for Fall/Winter 2009, so there’s a good reason why more male celebrities have started appearing in their pieces.
