So kawaii and perfect! The Ayumi Classic Seifuku Skirt has a gathered elastic waistband and contrasting trim as well. The skirt's waistband will stretch between 1-3" from the listed size. If you are in between sizes, we recommend ordering one size down for the best fit. This can be worn separately but looks the best worn together! There are two skirt length options: Micro - 14" and Mini - 17". If you need a different waist size, please mention your waist measurements in inches in the Notes section during Checkout.
