Zosia Mamet Debuts Brand-New Blonde Locks

Shoshanna's wardrobe may be preppy tween overload on Girls, but in real life, Zosia Mamet's style is pure Williamsburg. We're always admiring her quirky ensembles, not to mention her natural, unique beauty — and now there's even more to love! The star recently dyed her hair a gorgeous, rich shade of honey blonde that we're sure deserves its own name entirely.

Seen here on her way into an appearance on David Letterman, Zosia's new 'do is an example of how a color change can work in a big way (paging Leigh Lezark!). The whole light hair/dark brows thing is perfectly on-trend right now (thanks, Cara D.), and we can't wait to see where she takes it from here. Whether in long, soft curls or pulled back in a sleek, shiny ponytail, this look is an official addition to the Good Hair Day file.
