Get Zooey's StyleRay Mickshaw/FOX

Dana Weiss of Possessionista.com is InStyle.com’s correspondent on all things New Girl fashion for Season 3. Scroll down to read this week’s exclusive update on what Zooey Deschanel wore.

On last night’s New Girl, Jess Day (Zooey Deschanel) dropped a bombshell on her friends when she revealed that she has a long lost sister named Abby. The two Day girls couldn’t be more different, however, right down to their fashion choices. The show’s costume designer, Deb McGuire, planned for Jess’s vintage-inspired style to play off Abby’s edgier outfits.  And she did just that with Jess’s canary yellow dress ($145, amazon.com). “This was the perfect dress to contrast her from her uber-cool and edgy sister who is always pushing limits. And you know how I feel about stripes.” Can’t get enough of New Girl? Click here for outfit ideas inspired by the show.
