Looks great
I got this to make a memorial shirt for my grandmas funeral. I was worried it may be too hot but the fabric is thick and breathable. Easy to heat press on. Looks great! I actually want to buy another

Good fit, stays tucked.
A little long to wear untucked, but long enough to stay tucked through the work day.

Very small for the indicated size. Fairly thick, more like a Fall shirt than a Summer one
This is almost a 3 star shirt, but it has some drawbacks: 1. it is very short for it's size. I ordered an XX (2X) because I am not skinny. But I am not short either. This shirt would probably be tall enough for a very round 5ft tall man.. but if you are of average or slightly taller than average height you may find the torso length to be radically too small (unless you'r using this as a half-shirt for the gym or beach to show off those abs. :-D ... I am a bit more conservative in nature and so this shirt simply doesn't cut it. *so: if you have a VERY SHORT TORSO this may be a great option for you! :-) Thickness of fabric; the material is really thick. I was immediately getting warm when wearing this. It is advertised as a summer shirt but really it is more appropriate for Fall or Winter. Otherwise, the buttons seem durable, the stitching is adequate, and the price ain't bad. Lets call it 2.75 stars; recommended only on conditions indicated above.

Slim fit
I like the light material and styling. It does fit a little closely, so watch out if you're a bit large.
