*They run a bit large so order one size smaller than you normally wear* I thought I read the reviews but somehow I missed this point. I ordered two sizes smaller and will probably send them back. Great shirt! Exactly what I was looking for. I work in an office where I'm always on the go. I wanted a polo shirt that looked good, held its shape, and had a collar that didn't pucker. I don't really need slots for glasses or radio microphone, but I like the fabric and the hidden buttons under the collar. Very sharp shirt.
