Looks like Hannah and Marnie weren’t stuck dancing on their own this weekend; half of the girls of the Girls cast got the honor of being very special guests to last night’s GRAMMY Awards. Lena Dunham came in support of her boyfriend, fun.’s guitarist Jack Antonoff, while Allison Williams was none other than Katy Perry’s friendly date to the ceremony. While the two costars couldn’t have dressed any more differently, Lena looking casually radiant in a floor length yellow dress and Allison glamming it up in a sultry KaufmanFranco metallic gown, we felt equally inspired by both looks to find a more practical and budget friendly version of each.
