Well I bought this for a three-year-old who is still in the has occasional accident range of potty training - we wanted pants that she could easily get on and off over her panties. These, however, fit more like a pair of tights than leggings, they are snug in every measure - waist, ankles, fit through the leg are all skin tight. I even went the next size up for my toddler and while there was more length to work with, the fit was still much tighter than her leggings from other brands. We still use them but I don't send her to daycare with these and have to remind the adults on the household to help her get these on and off if she asks to use the toilet. That said these pants are super cute and they seem to be well made with a nice balance of softness and stretch, I just wish they had a little more stretch or a more generous cut in their construction. Or just advertise them as really opaque tights, one or the other. We tried the next size up, waist is bigger, legs are longer but the fit through hip, seat, thigh and all down to the ankle is still skin tight.
