Most men and many women I know love t-shirts. And no-wonder, a t-shirt is a short sleeved, knit top without a collar. They come in a variety of silhouettes and necklines.  They are comfortable, easy to wear and appear casual, laid back and easy going. However, all of these great reasons for loving them are also great reason’s for not wearing them to work. When you are trying to impress your boss, a client or show that you are focused, on the job and effective in your work, why would you want your clothing to contradict that message and effort?
