At work or even walking down the sidewalk you've probably noticed somebody dressed a certain way and and made an instant judgment of the person. Initial reactions aren't always accurate, but they are important, especially at work.

These snap judgments people make impact your chances of landing the job you want. In fact, one study found that nearly 40% of hiring managers indicated they decided not to hire someone because of how the person was dressed!

Today's workplaces have changed considerably and there is now a wide range of what is considered acceptable attire. For job seekers this can present a challenge because what is deemed acceptable can vary by employer. Some may expect suits whereas others could be proponents of casual dress. These differences matter because each company has its own culture and norms.

There is one simple thing you can do before an interview to prevent this from happening to you: ask what to wear. It may seem like an odd question because it was once always considered appropriate to wear a suit to an interview. However, this is no longer the case. Also don't make the opposite mistake and assume that it's okay to dress down because the company has a casual environment.

What you wear will provide cues as to your personality and if you will be a fit with a company. Don't leave this to chance. Better to ask one simple question than get odd looks when you walk through the building to your interviews wearing something that makes you stick out - in the wrong way.
