I know you've heard this before, but you really need to consider what you wear to interviews. If this weren't an issue, folks would stop talking about it. But I have sat in on interviews lately and been really shocked at how inappropriately some people choose to dress for interviews, the most professional activity you're likely to be involved with in the near future. If you can't get a new interview outfit, raid friends' or relatives' closets. You only need one suit and can wear it to all your interviews. You'll be the only one to know.
In dressing for an interview, you should choose to wear the most professional outfit you own. It shows you care and are taking this interview and the opportunity to teach students seriously. This is not the time to look your most trendy, most sexy, most anything other than professional. All you get is one impression. Make sure it is a good one.
Ladies, I'm just going to say it - an interview is no place for cleavage and thighs. Under your suit, your top should be modestly cut and lace tops are not appropriate. If you wear a skirt, it should be long enough to cover your thighs even when you are seated. Again, maybe not the most trendy or most fashionable, but it is most appropriate. Which is your biggest concern here.
Men, you might not want to hear this, but you need to wear a tie. Why? Why not?! Why would you take a chance and not dress your best? Ties should be conservative, avoiding characters or extreme colors. Long sleeved shirts are most appropriate, even in the summer.
Bottom line: interviews are the place for conservative business suits. Conservative colors (black, navy, gray, brown) are best. Interview attire plays a supporting role in your job search. Make sure that role helps you get the job.
