My 10 year old is very tall and skinny and wears a size 14 pants. I buy skinny jeans and they are long enough but fit like loose fitting jeans. All the pants and pajamas we buy have large waists, which I have to wear most of the time. These winter trousers 11-12 fit perfectly. Long, tight and the suspenders for holding are very comfortable. He loves them and says they keep him warm at 10 degrees.
