Just wanted to share my experience with the sizing on these shorts since I know that is often of interest. I measured the rise on RTW shorts that fit my son well and then sewed the 2T. They are very long but the rise is perfect over cloth diapers. He wears 24-mo in RTW but if I put him in a disposable diaper he can fit into 12-18 month RTW. My elastic circumference is 18" after being sewn together and there is no gap, and no visible diaper. Hope that is helpful.
