Interview attire for humanities/arts at a prestigious program?

[teethwax]

I just got an interview invite at one of my dream programs (playwriting MFA), and I have no idea what to wear.  It's an Ivy, and I've never been to one before, so I'm pretty confused/nervous about what is appropriate.  I'm going to have two interviews over two days, so that makes things more complicated, too.  I'm a guy, and I own exactly one suit (dark gray), but looking at some of the threads about women's attire, I'm wondering now if a suit will be too stuffy or odd. Would something like a sweater/button-down/wool pants work better? Should I wear a tie also? Help!

I'm surprised at the myriad threads on attire. It's an important event, look nice.
