I literally spent 2 days reading reviews when considering this purchase given the price and reviews. I gave up and ordered the medium one for my 8 year old son who wears a 7/8, he's tiny for his size but still ok for an 8 year old. Somewhat thin definitely not thick sweatshirt material. A coat/jacket is also required. Something like a box, nothing underneath, just there, like in childhood, they drew a shirt on a figure. Anyway, my 11 year old who weighs 84 pounds was able to put it on with no trouble. Don't feel like going back so I only wash a couple of times and it should shrink because the color is nice and hopefully can grow into it in 2 years lol.
