This listing is for a slippery, silky feeling, one-size dress straight from Korea! I couldn't read the tag, but the fabric feels like rayon or a rayon blend. Measures about 42" long from back of the neck to the hem, and 20" wide at the waist when laid flat. It looks super comfortable for wearing around the house. While the tag says "one size", it is probably medium to large in woman's sizes.
