I read a lot of reviews before purchasing these. I'm a female that was looking for thicker white t-shirts to layer with cardigans. Unlike other reviewers, my shirts are definitely authentic and have an embroidered alligator, which I could live without. They are a nice thickness but they are a slim-cut. I would say they the run at least one size too small. I am returning for a size bigger as I was going for a looser fit tea.
