I had the size adjusted once because it was too big, but I've returned it to its original state. There are no traces of the adjustment. I've worn it about once or twice. The waist is around 70cm and up, and the back waist is elastic. It has a lining skirt, so it's not see-through. It's made of smooth, silky satin fabric, so it seems like it would be cool to wear even in the summer. Instant purchase is OK. Please check the condition of the product in the photos. Due to shipping costs, it will be folded compactly for packaging, but please understand. -------------------------------------------------- GU / GU / Satin Mermaid Flare Skirt / Satin / Satin Skirt / Mermaid / Mermaid Skirt / Flare Skirt / Flare / Skirt / Long Skirt / Long / Satin Fabric / Floral / Flower / White / Ivory / Beige / White / Natural / natural / Elastic Waist Color...White系 Color...Beige系 Pattern...Floral Season...Spring/Summer
