We ordered these for bathing suit cover ups. I did order my daughter's ( 5ft 95 lbs) in a small due to some reviews saying it was tight fitting. It is not tight fitting and I should have probably went with the extra small for her. But overall, it was still great for the beach.
I’m an XL all day everyday. I got my size because reviews said tts but even in a suit it hugs too much. I don’t mind some tailoring but I do advise to size up one. the fabric was much like the economy Gildan. It wasn’t especially soft and for the price I guess I hope for more.
