<p>Before u visit the school, visit the school’s website/ student handbook to see what the students wear. Use the school’s student dress code as the MINIMUM standard for what to wear at the visit/interview. Personally, I would make my S wear a tie, no matter what, but he is used to wearing one.</p>
<p>BOTTOM LINE IS:
U want to look like u fit in. School interview is not the time for sartorial self-expression-- save that for AFTER u get accepted.</p>
