Since it's see-through with just one layer, you can wear something underneath. You can wear it as a camisole dress in midsummer, or pair it with a turtleneck in winter. The waist has elastic, and the back is a lace-up design. There's a slight snag in the thread, so I've selected "with stains," but I don't see any noticeable stains. I bought it for about 8000 yen.
