While the college campus may be an open forum in which to exhibit your flair for the latest in fashion style, the interview is not the place to do so. With very few unusual exceptions (such as some tech companies or creative ad agencies), sandals and sweatshirts are out. Business suits are still in when it comes to interviewing. I don't like wearing a necktie (noose?) any better than the next person, but it is still a fact of life in interviewing. Even though many companies have relaxed the internal company dress code, interviews still follow the conservative standard. This is not a time to attempt to set a new trend.
Campus fashions and work fashions are two different worlds.
Most college grads are woefully underprepared with proper interview outfits. They feel they can "get by" with what is already in their wardrobe. Usually not. Dress for the world outside college is quite different from the campus scene. Remember that stylish is typically not conservative. Conservative is "in" for interviewing. Why? Because you should be doing the talking, not your clothes. If your clothes are a distraction, they are distracting from who you are in the interview.
This is not to say that you need to go out and buy a whole new wardrobe. Go for quality over quantity. One or two well-chosen business suits will serve you well all the way to the first day on the job and beyond. Then, when you are making some money (and have a chance to see what the standard "uniform" is for the company), you can begin to round out your wardrobe. For now, no one will fault you for wearing the same sharp outfit each time you interview. If you desire some variety within a limited budget, you might consider varying your shirt/blouse/tie/accessories as a simple way to change your look without breaking your wallet.
For those of you who need a quick review of the basics, follow these guidelines for successful interview dress:
If you are still not sure how to dress for the interview, call and ask! That's right—call the employer. But this is one time when you do not want to call the Hiring Manager—instead, ask to be put through to Human Resources and say:
"I have an interview with _____ in the _____ department for a position as an _____. Could you please tell me what would be appropriate dress for this interview?"
Sure, you run the risk of someone in HR thinking you are an interview neophyte, but that's a lot better than having the Hiring Manager distracted by inappropriate interview dress. While many work environments have shifted to business casual as the workday standard, business suits are still the interview standard. When in doubt, it is almost always better to err on the side of conservatism.
One final note on interview dress: while it goes without saying that your interview clothes should be neat and clean, very few interviewees give the same time and attention to their shoes. Shoes? Yes, shoes. I am aware of at least one Corporate Recruiter who forms first impressions based solely (pardon the pun) on shoes. This person does not have a shoe fetish—he subjectively judges that those who pay attention to details like shoes are also likely to be diligent in their work life. And it is not just that person's opinion. Many have said that you can judge a person by their shoes. You will find that many ex-military officers (many of whom have found their way into management positions in corporate America) are especially aware of a person's shoes. It is not enough to be clean and pressed. Make sure your shoes are conservative, clean, and polished.
