I absolutely love these shirt. They've become some of my favorites. They're incredibly soft and comfortable.
I ordered a XL (for measurements 36-29-36, 5'8" and 184lbs.) but I could comfortably go with a large if I wanted something a bit more form fitting. But I like my shirts a bit loose and flowy, so I like to size up to the large on these (which fits me much like the model pictures in the listing). I've ordered several colors and both the long and short sleeves and they've all been wonderful.
Overall, I would recommend and would certainly order these again in the future.

These tee shirts are so soft and comfy, I liked it so much, I ordered a second one after receiving the first. I ordered a large, which I normally wear. I'm 5'7'' 168lbs. The fabric is thin (in a good for summer way) and stretchy, and it fit very snug to my body. I decided to keep it, since I will be wearing it under a jumpsuit and it will be mostly covered. I ordered an L the second time around in a different color. It is not big, by any means, but has enough room to hang perfectly, and my bra lines aren't showing. The fabric drapes wonderfully.

It's is a basic t-shirt. Now that I've received it, I'm honestly very happy with it. It fits me nicely and is very soft. Its a bit summer-time thin, but not in a bad way. It is not tight in my shoulders as is sometimes the case for me and cap sleeves, so that is great.
For reference, B 36", W 29", H 37" 150lbs, 5'5" and I ordered a medium.

This is a great, all-around tee. Great for layering or by itself. Fits as expected and comes in a multitude of colors. I may buy a few more in different colors. The fabric is soft and drapey, but not too much, and it breathes well, so much so I wear it to my exercise class. Washes beautifully.

I have been purchasing and returning tees from different brands. This one is awesome! Yes, the material is thin, but it's soft with a good length and doesn't show sweat stains. Recommend. Nice material. Soft comfortable and Fits well.
