I couldn't make up my mind on the size to order, due to some of the reviews stating to order up or order down.  I ordered in my regular size, 2XL, even though i am now losing weight.  I figured if i ordered my regular size, the shirt would fit loose, and i could wear with leggings.  Well, this shirt was loose on me, even though i wear a 2XL now.  I am chesty, 44DD, and there was a lot of slack in the shirt.  I could wear it now, and it wouldn't look bad, but i can tell there was too much extra flowy material.  I should have ordered a 1XL, to get the more fitted look, throughout the bust area, but flowy look, from the waist down.  Otherwise, the material is very soft, and the thickness is great... not see through.  Definitely, order a size down, unless you like extra-extra room.  I gave this 5 stars, even though it runs bigger than expected.  I really like the shirt overall, and would buy it in other colors.  I guess it's better to receive it in a size with a little extra room, rather than it being too small, to fit.
