These knit shorties fit as a loose fit tapered short on the smaller end of the size range and fit more like a biker short as the child grows. The sizes grow from a longer short to a shorter short. There are two short lengths and two short fits (relaxed or slim fit). The pattern also includes two skirt options (a full circle skirt* and a half circle skirt). There are so many fun summer options with this versatile grow with me pattern!
