Based on the reviews (one size up and some a size up) and our lack of time before finding this shirt I ordered 2 sizes, a 10 and a 12. Size 12 arrived first so we opened it up and tried it on. My son normally wears a size 10 (M), weighs 71 pounds and is 4 feet tall. At a size 12 it has room to grow but doesn't look too baggy and is a bit long but not sloppy. He could probably wear a size 10 but I didn't open the package for him to try on because I like the look of a size 12. The quality is excellent. I'm pleasantly surprised. I've looked at so many t-shirts on Revain and Etsy and this one got the best reviews and now I know why. It's great and the colors are perfect. I can't wait for my son to wear it to Hawaii.
