According to this article in Miller-McCune by Tom Jacobs, if you need to focus on a tricky task, the best thing to do is wear a lab coat -- it actually makes you feel smarter.

While much research has looked at how our wardrobe influences the way we're perceived, their study examines its impact on our own thinking and behavior.
