'Limitless': Everything You Ever Wanted to Know About Brian’s Crazy Sweaters

Without fail, Every time we watch CBS’s new hit Limitless, we’re left with two pressing questions: What would it be like to take NZT (duh), and what the heck is up with Brian Finch’s crazy sweaters?

While we can’t answer the first one — it’s a fictional drug, you guys! — we did manage to get to the bottom of the second by grilling wardrobe designer Sarah Mae Burton… and it’s not just because actor Jake McDorman is perpetually cold.

“Brian is a guy who’s in this very serious environment within the FBI, but he isn’t that, so he’s decided he isn’t going to dress the part and he’s just going to be himself,” Burton explains in brief. “So we always look for things that have a little bit of character and life to them.”

Limitless airs Tuesdays at 10 p.m. on CBS.
