I ordered 2x sizes larger than I needed, in hopes he could wear them for a while since $20 is expensive for 3 onesies... But they were fitted! The arms were too tight and there is no stretchy give to them. The monster pattern is very cute, but the other 2 are a waste, they look like the other cheapy onesies you'd get anywhere, so you really pay $20 for one cute onesie. I would not buy any more from their collections.
