You might think about this for a college interview (maybe it would work for a job interview, too):
Look at the college's brochures. They always show happy, intelligent-looking students. Look at the pictures on the front cover, or in other prominent places. The college's marketing department should be projecting the image of the kind of student they want.
Now, look at what those students are wearing, and the attitude they're projecting. I think if you go about one step more conservative, you'll probably be dressed correctly.
Don't forget about hair, makeup, jewelry, and accessories. Even if the college doesn't care how many body piercings and hair colors you have, such items could be distracting. Above all, your attire should draw the eye towards your face--unless you want the interviewer to be paying attention to some other part of your body.
Here are some college websites. They actually don't have a lot of photos. Some of them cycle through several photos, so you may have to reload the pages a few times to arrive at a picture that shows the students.
This campus actually shows male students wearing ties, even coats. The female students are required to wear dresses or skirts. I think this would be considered a very conservative campus.
This campus appears a little more casual.
This campus is also casual--look for the fashionable eyewear.
And now, a
corporate website.
