It's been a busy week for fashionistas, with the A-list showing off their impeccable style as they turned up for the premiere of Southpaw last night in New York. Rachel McAdams stole the show in a black cut-out midi dress, while Zosia Mamet took a fashion risk (that definitely paid off) in navy co-ords. The men weren't afraid to make a style statement either, with 50 Cent looking dapper in a green satin suit, and Jay-Z working the casual look in faded denims and a grey T-shirt.
