Both Rihanna and A$AP Rocky are certified fashion killas. Besides being "Phresh Out the Runway," RiRi's got a gig designing women's clothing for River Island. And we've been applauding Rocky's style since his meteoric rise began, crowning him both the most stylish celeb of 2012 and the style king of NYC rappersSo when the Diamonds World Tour arrived at the Barclays Center in Brooklyn, it was pretty clear that the die-hard fans of both acts were going to show up in their flyest gear.

The energy outside of the arena was electric as early as 6pm. Insanely dressed members of the Rihanna Navy and dudes who clearly took style cues from the Harlem-based A$AP Mob milled about, trying to meet up with their friends in the crowded pavilion and then taking pictures of each other in front of the stadium. We posted up and snapped the wildest and freshest outfits on the dudes who were there, so click through for Street Style at The A$AP Rocky and Rihanna Concert at Barclays Center. Make sure to zoom in to get a detailed look at each kit.
