Runs large with gaping arm holes.
Size: Large, Color: White
This runs extra large and the arm holes are gaping. You can see your undergarments through the arm holes. I am hoping that the shirt shrinks in the wash.

A little thin but very cozy and comfortable, soft fabric
Size: Large, Color: Navy
Thin but super soft and extremely comfortable. I would have liked the fabric to be a tad bit thicker, thus the four stars instead of 5. I wore this with a denim blazer. It is a beautiful navy. I think I will order a size larger than normal and maybe then the thinner fabric won't be such an issue. Nice sleeve length, not too clingy.
