My son is not fat, but he has a strong build. He has very thick thighs and a small butt. Big calves too. He mostly has tree trunks instead of legs. Finding skinny jeans that really suit his body type is difficult. Where we live, you can't wear sweatpants and basketball shorts all year round. So far they have withstood a very active child outdoors. I had no issues with the fit in general other than the length. But that's mainly because he's 4 years old and wears a size 7/8. There's nothing a sewing machine can't fix.
