Thank you for viewing! This is a light, thin, sleeveless top in a refreshing light blue color, offering a comfortable feel. It can also be used as a petticoat. - Color: White (light blue) - Size: M (Free) - Material: 100% Cotton I think it will also help prevent see-through of dresses, etc. It's also comfortable to wear as loungewear. This itself is not see-through, and it's 100% cotton, so it feels good. Size (flat measurement) Shoulder width (since it's a tank top, I'll measure it like a tank top): 38 cm Body width: 44 cm Length: 100 cm Since it's cotton and stretches, the manufacturer lists it as M, but I think it's OK as a free size. Although it's a new, unused item, it has been handled by people, so please purchase only if you understand. #CottonLongDress #LongPetticoat #ComfortableWear #LazyDress #MUJIStyle #CarefulLiving
