Lizzy Caplan has come a long way since her Janice Ian days.
Yep, if you're unfamiliar with the Mean Girls alum, then we bet you hardly recognized her. These days, Caplan has traded in her edgy on-screen style for a much more glamorous red carpet look.
The Masters of Sex star proved she could hang with best dressed crowd when she wore a dramatic black-and-white Donna Karan Atelier gown to the 2014 Emmys. Drama aside, the actress let her hair loose with an autumn-inspired Marchesa midi at the 2014 TCAs.
We're not sure how her Mean Girls character would feel about a butterfly-print gown, but we adore the star's Valentino sheer gown at the Critics' Choice Television Awards this year. Ditching the feminine prints altogether, Caplan opted for a playful color-blocked Roksanda ensemble at a 2014 TCA Press Tour event.
Rounding out our top pics, we have the actress in an awe-worthy Emilio Pucci creation at this year's Golden Globes. It's a little fashion-meets-Art Deco, don't you think?
