So many big decisions to make ahead of festival season… Desert or city? Full badge or single-day? Elbowing your way up to the front of the crowd, or hanging out in the back in a nice, comfortable lawn chair? (Okay, maybe my age is starting to show.) And that’s before you start thinking about your wardrobe for a heavily Instagrammed weekend spent mostly outdoors beneath a blazing-hot sun (unless, you know, you’re lucky enough to be hanging out in an air-conditioned VIP tent somewhere). The sartorial solution? Aéropostale’s new collaboration with talented songstress Sabrina Carpenter: Carpenter’s picks are guaranteed to keep you looking—and feeling—cool all season long.
