Read the reviews and saw that several people mentioned that the sweater was thin.  Last year I got a cable knit sweater from the same maker and liked it so I wanted to try it. I decided to order a large instead of my usual medium, thinking a roomier fit would keep it from being see-through.  No joy.  This should be listed as a layering undershirt.  It is soft and feels good but I can't wear it unless I am wearing something over it or a thick cami underneath.  I was disappointed.  If I had bought this in a store I would return it.  Now I wish I had gotten the right size so it would be better for layering.
