Unless otherwise noted in product descriptions, sizing for all skirts is as follows:
XS - 24" Waist, 18" Length (Size 00) - Will fit 36" hips
S - 26" Waist, 19" Length (Size 0/2) - Will fit 38" hips
M - 28" Waist, 19" Length (Size 4/6) - Will fit 40" hips
L - 30" Waist, 20" Length (Size 8/10) - Will fit 42" hips
RECOMMENDED: For a more custom fit, please leave your measurements in the order notes. Measurements needed are natural waist (where the skirt will sit), hips/rear (at the widest point), and finished skirt length (this can be done by holding measuring tape at waist and letting it fall down, noting where your desired length is).
