These are worn instead of skirts (with briefs underneath in case they need to change to skirts). Although these can be worn year after year, most will find the growth patterns make this a 1 season garment. These are worn at the natural waist (not hip-huggers), and the inseam measurement should take the leg from the highest point between the legs to the floor when barefoot. Inseams are in 2" variants. When in doubt, chose longer.
