<p>As long as the kid is comfortable in the clothes, pretty much anything. Better to be yourself than to pretend because admissions is looking for reasons to admit you, not reasons to exclude you. That point needs emphasis: admissions is always looking for what’s good about a kid. The bad kind of sticks out, like low grades, low test scores, inability to speak coherently, etc. But lots of kids put conforming to their or their parents ideas about how they should act and what they should say over letting their particular light shine. The clothes don’t matter, with the obvious caveats.</p>
