You know what they say: You only have one chance to make a first impression.

At career fairs, the most obvious and noticeable way to make this impression is through what you wear. 

If you wear something inappropriate, the employer is bound to notice, and this could seriously impact your chances with them.

“I think for women, it tends to be wearing something too tight, too short, too low-cut,” said Loni Pringnitz, program coordinator in the College of Human Sciences student services.

“After every career fair, we send out an employer survey, and two career fairs ago, there were a lot of [negative] comments back from employers about how our female students were dressed. Too conservative is always better than being flamboyant in a situation like this.”

Men, that doesn’t mean you don’t have boundaries too.

“For guys, no matter what age you are, don’t wear sweatpants,” Pringnitz said. “Sweatpants, sweatshirts, baseball caps, they’re all unprofessional, and I’ve seen it more than I’d have liked.”

Make sure to press your shirts so you don’t show up in wrinkled clothing.

Freshmen can get away with being the most casual, since they’re primarily there to get their feet wet. 

Employers are usually more understanding with them.

It’s more nerve-racking to try to talk to professionals when you’re younger and haven’t had experience yet, so it’s typical for young students to have a little more leeway than other students.

Students attending career fairs need to realize they’re under the scrutiny of all of the attending employers. 

For girls, jeans and a nice top with a scarf is acceptable. Skirts and dresses are also generally a safe bet, but stay away from high heels.

The career fair is held in Hilton Coliseum, after all. 

There are a lot of stairs: You’ll be walking on concrete, and you’ll most likely be doing a lot of walking. 

If you’re wobbling around, you’ll look foolish.

Try to stick with footwear of a reasonable height. 

Younger men can wear khakis and a nice shirt or dress pants and a button-down shirt, plus nice shoes will really tie the outfit together. 

Senior men should be wearing a suit since they’re looking for full-time employment.

For girls, don’t overdo the makeup: “I think that heavy or too dark of makeup is a turn off to most employers,” said Cathy Hockaday, adjunct assistant professor in the College of Human Sciences. “Too big of earrings or too many bracelets can also be a distraction from what the person wearing them is saying,” 

More advice from Hockaday for both men and women: “Flip flops and sandals are also not good choices for males or females who are trying to make an impression on future employers. … While upperclassmen should be the most conservative in their dress, I think it is always good practice for all students to dress professionally. 

Tattoos should be covered up as much as possible, especially if they are not small and discreetly placed.”

Even if you’re not actively seeking a job or internship, professional image is still important.

You’re there to network and impress the employers, not to make them gawk at your choice of clothing.

“I think men’s dress attire is easier than women’s, but everyone needs to put thought into their outfits,” Pringnitz said.

“Get a second opinion and check with your friends or roommate before you leave the room. Always get feedback if you’re uncertain,” Hockaday said.

When you bring 160 employers under one roof, there will be people paying attention to what you’re wearing, so, when all else fails — play it safe.
