Amoralle lace skirt S/M

Flexible skirt. Worn twice. Some 3 small spots have appeared on the back (where the draping is) that I couldn't wash out by hand. They are visible from the left side, but not noticeable from the right because the lace is patterned. The front is originally where there is no draping, but it can be worn on both sides. Indicated size M, but it also fit me in size S. The waistband is elastic. The skirt has tulle underskirt. Waist circumference 64cm. Skirt length 93cm
