This underwear is soft and generally comfortable. I have two children who have tried them. One weighs 51 pounds, has wide hips and a round butt. The other weighs 49 pounds, has narrower hips and a flatter butt. A 51 lb kid says they are a bit tight for him. They're better for my flat-bottomed kid. I don't know if this helps but thought I'd share it.
