Thanks to the other reviews, I ordered a 5XL (!) and I'm really glad I did. Fits perfectly (I'm usually an 8/M but wanted it a little loose). Taking off a couple of stars because the button to secure one of the sleeves when rolled up is missing. Annoying. A spare button is attached inside the shirt so I can use that to sew on myself, but the fact that I have to do that is stupid and a pain. Material is soft, just what I was hoping for.  I bought a couple of these (two different brands since the sizing is so strange) and the colors in the pictures are different than the shirts actually are. While this blue one looks darker ad bolder in the pic than it is (very soft, light colors IRL, which is fine), the "peach" one I bought is actually almost red or dark pink, so the pic makes it look A LOT lighter than it really is. I like the fit and length of this one though, so the other one (Match brand) is going back.
