I ordered a size 36” for my boy as he has a tall body. It is huge width ways and actually measures 40”. I ordered the biggest size for the length, as my boys school jumper measure 36”. The length of the school jumper is 15” from under the arm to bottom and the beaver top is only 13” at the front, 14” at the back from under the arm to bottom. The length will not last until he leaves beavers as already on the shorter side. Just be warned if you have a taller child the sizing is may be too big width ways and not long enough. Unfortunately I can’t say about the polo shirt I ordered as they sent me a cub jumper in error!!!
