"The Americans" premiered on FX on January 30th, and the world is simply abuzz! We were so excited to see Keri Russell taking on this new series (we loved her in "Felicity"!) that we couldn't wait to watch.

Naturally, we've noticed her style as she promotes this new show, and we're nothing short of obsessed. She's taken her famous curly locks and made the waves softer, while wearing classic looks and sleek dresses. We thought it would be fun to compare her style now to her style back in her Felicity days, and see how she's transformed!

Keep your eyes on this Golden Globe winning actress, we have a feeling The Americans is going to be huge. Click through the gallery above to see her style then and now!
