My slim and tall 5 year old daughter wears a size 6 pant. Normally a size 6 is perfect in length and a little loose in the waist. We ordered a size 6 and they were very difficult to put on, too tight at the waist and short at the ankle. The material quality is good for school pants. We're ordering a size 8 to try on her as we love the idea of the elasticated waist.
