What to wear to the interview?

<p>I know this seems like a silly question but I'm not sure what to do. My interview is tomorrow. Everything I read says that I should dress up a bit, but I get the impression that this isn't a super formal interview. My confirmation letter said to wear "comfortable walking shoes" (it's a "large and hilly campus.") So I was thinking of wearing sneakers (converse.) So should I wear a (casual but still nice, knee-length) skirt and sneakers? Nice jeans and sneakers? Something else? I'm probably stressing about this more than I should, lol.</p>

<p>Oh, and the interview is important. All applicants are required to have one.</p>
