Fresh off the stage at this weekend's The Sound of Change Live concert, Beyoncé traded her costumes for the coolest kind of casual wear. While strolling with husband Jay-Z in NYC, the star showed off a polished play on leather shorts that could convince even the Summer-leather skeptics to get in on the trend. She walks the line between sophisticated and effortless with details like sunglasses, a great hat, and a Helmut Lang blazer to dress up her basic white tee on top. And while you could opt to finish the look with flat sandals or even a sporty pair of sneakers for a more comfortable play, you might just want to take a page out of Beyoncé's book and style with bright heels for an attention-grabbing finish.
