Children's Place has elastic waist pants in various types. They have a waist that is like a sweat pant band, no buttons or zippers and they sell them in jeans, cargo, or corduroy. Some of the styles fit narrower then others and can be tightened with a drawstring. I have a 4 year old boy who has physical disabilities, he can not do zippers or buttons and is extremely underweight because of his feeding difficulties. Finding pants has been a massive challenge! We can't do pants that tighten inside with buttons to make them narrower. The jeans at TCP seem to tighten/fit the best for him, they are long and skinny, he can wear a 4T in those. We also do a lot of track pants, some different style fit narrower as well. We have some Nike ones that are awesome but I can't find that style again and all other current ones, are too big. it is hit or miss with those. I hunt them often at TJ Maxx.
