Maybe not all interviewers endorse this idea but wear something comfortable, something that does not make you fill like you are someplace where you don’t belong.  Many interviewers emphasize that it is what is inside that counts.  College admissions interviewers say that they do not report on how the interviewee was dressed.  However, they would not like it if you wore something that is out of place, such as wearing swim shorts to a cafe for the interview.  College admissions interviewers also would not like if you showed up smelling with bad body odor.  It is not a good idea to wear something too heavy since you will sweating a lot and would not be able to concentrate on the interview

Try to be comfortable and be yourself.  That’s what they want to know.
