As a body language expert I have studied the research on professional attire for many years. Here is an article examining some of the research that indicates that you can dress to improve your confidence and how others perceive you.
A scientific argument for dressing a little nicer at work
Last year, the phrase "enclothed cognition" — an offshoot of "embodied cognition," the idea that aspects of your thoughts are shaped by your body — entered the b-school vocabulary. The term came from Adam D. Galinsky, a professor at Northwestern's Kellogg School of Management, who found that when people don a white lab coat they believe belongs to a doctor, they become more focused and careful — effectively a little smarter when performing cognitive tasks.
Of course, we're not implying you should show up at the office tomorrow in a white coat with a name tag that says "doctor, not artist." But it's worth thinking about what symbolizes smart and effective in your own office.
This one is directed at those who are wearing jeans and sneakers in a mostly slacks and oxfords office — meaning, those who tend to dress more casually than others. Even if you're not violating a dress code, some evidence says dressing "properly" has an impact on how you see your own skill set.
