Although the DVD for Glee Season 1 doesn't hit shelves till September 13th, we were able to nab a sneak peek from the extras! In the video, Glee's costume designer Lou Eyrichtalks about the importance of on-set style: "Clothes help define who the person is by something as simple as a skirt length or a shoe they put on." As far as Lea Michele's character, Rachel Berry, goes, she's "a little bit nerd, fun and colorful," Eyrich says. Check out Berry's "hangers full of socks" in the video now, and stay tuned for the season two premiere, airing on September 21st at 8pm EST on Fox, where we hear that the opening number will be a rendition of Jay-Z and Alicia Keys's "Empire State of Mind"!
