I bought this underwear for my 2.5 year old boy. He is a tall boy. This underwear fits him weird, the cut is all wrong, they are cut too long in the crotch-leg area so either he has to wear them super high and the elastic band shows above his pants, or I have to fold the elastic band a few times to avoid this, or he has droopy underwear with zero support. Also the elastic band is cut to wide for the sizing, so they don't stay up anyways. It is too bad because the colors and cotton are nice.
