Shirt is tight in several places.  I am a big guy so it can be hard to get the right shirt (6' 3" and 215 lbs).  That said I think this would be a tight fit for many people.  Any middle aged guy with a gut will probably have some trouble with this shirt.  It is nice material and seems to be well made though so if you are slimmer for a guy or average sized for a woman it would probably fit just fine.
