It's the final countdown to the premiere of Arrested Development season four--May 26 on Netflix, in case you didn't already have it circled on your calendar--and we here at Fashionista understand your excitement... more than you'll never know. Since a lot of the humor comes from the characters' costumes (who can forget Tobias dressed as a pirate, or Lindsay's "Slut" tank top?) we hopped on the phone with the series' costume designer, Katie Sparks. We asked her for all the details about working with the cast--and we think we may have gotten a tiny hint or two out of her about the new season. Oh, and we definitely asked her about those denim cutoffs--you know the ones. We just blue ourselves in excitement.
