Yesterday, avid tweeter Bethany Cosentino, leader of Best Coast, announced on the blue bird board that she has designed her first clothing line for Urban Outfitters.“Stoked to announce my first ever clothing line! Bethany Cosentino for @urbanoutfitters! Drops in May,” she tweeted. The post showed a photo of a model wearing a dress, we suppose, from the collection. It's not the first time the clothing chain has called upon a rock star; in 2009, they worked with Kim Gordon from Sonic Youth. In fact, we also got word the bassist will be working with the brand Surface to Air.
