When we spotted Girls star Allison Williams hanging out with fellow star/creator Lena Dunham at the L.A. Loves Alex's Lemonade Celebrity Wine and Food Event in Culver City this weekend, we knew immediately where she nabbed the adorable striped seersucker dress she was wearing. It's this A-line sun dress from American Apparel, which Williams paired with cute pointy-toed red flats. And you can grab your own for $70 here! Seersucker is the ultimate summer fabric, so we recommend rocking this adorable frock before fall's first official cold snap arrives.
