<p>You are WAY too nervous about interviews. IMO, you sound like you have interview-phobia. So, just don't do it!! </p>
<p>If you decide to go anyways, I recommend wearing that nice GAP shirt and some khaki pants.</p>
<p>The shirt you are considering is nice, but it is going to match better with khakis. You should find a brown belt, because you will want to tuck in a dress shirt. Another option for interview clothes is to wear a nice sweater or long-sleeved shirt. Check out a nearby Polo outlet to buy a shirt or find a comfy sweater. Don't over-dress, just look nice. Sagging is a fashion faux-pas, and unless you are interviewing for a surf-shop pacsun will not do. </p>
<p>Interviews are not a big deal. If anything, it will probably help for WU because it can show demonstrated interest. If you want to be a bio major, talk about a prof. you have heard of there or talk about a unique class WU offers others don't. Discuss(for a LAC) how the wide range of subjects and love for learning really interests you, and how everyone seems to play a role in the community. If you are particularly interested in an EC, for example the student newspaper, discuss how you would love to take part in formulating it. Discuss how socially you can benifit from the university. If you have enough passion for a university, it will show in the interview. Interviewers want substance, not BS answers. If you like city life, don't say "because there's so much to do." Discuss the wide ranges of cultures available and how different it is from your background, etc. Or discuss the research available, internships for students, study abr., or museums/theaters/art.</p>
<p>Good luck!</p>
