They stretch a bit but aren't snug like regular spandex. They are smooth and slightly cottony. I love Kid Nation clothes and they come in different sizes. These are the largest L (8/10) among them. They almost fit like an adult x-small or XL-teen. They are more form fitting on a 100 lb woman, although the shoulder seams may be 1cm slimmer, but they can definitely be worn. Or maybe they wanted a very free spirited look? I'm hesitant to recommend going higher as Kid Nation tends to run true to size and it's possible my size was a manufacturing error. However, if they are too big, children will later grow up to wear them. Plus they're so comfy the kid still wants to wear them ha.
