DS is very petite, think 5’2” and maybe 105 lbs as a high school senior.
He’s found a few stores with adult xs slim fit shirts that fit him, and can occasionally find jeans at a single store. For most of his clothes, like khakis, suits, sweaters, athletics, etc, he just buys from the children’s section. Even a children’s size 14 can be too big.
Realistically what do young adults who stay very small do when looking for clothes? Being a college student shopping in the kids section seems crazy, but he isn’t really an adult size.
