I've ordered these t-shirts previously. The ones from two and fours years ago are still functional and whole but have become overly dingy and the collars no longer sit flat so I ordered new ones. I was surprised by how thin they are. With the older ones I would be comfortable wearing them around the house if need be but with these I may as well go shirtless since they are pretty much see-through. Given that they are intended to be worn under another shirt they serve their purpose but I am not pleased with them.

After washing these I now have two regular length t-shirts. Changed from 3-stars to 1.
