Allison Williams wrapped up her breakout role as Marnie Michaels in HBO’s Girls and never looked back. Despite growing up a scion as the daughter of news anchorman Brian Williams, the actor came into her own as the lovable, often insufferable best friend of Lena Dunham’s character, Hannah Horvath.
While Marnie certainly had her share of fashion hits and misses, off-screen the actor has become a fashion girl in her own right. A regular on the red carpet, gala circuit, and front row at fashion week, Williams always catches our eye. From event to event, the star slips into a huge range of looks, but always stays true to her signature girl-next-door meets classic feminine.
