This is a one-piece room wear from un'un'cool. I've worn it about 5 times as pajamas or loungewear. The inside is soft, and the outside has a terrycloth-like feel. There are buttons at the chest and ankles. The ankles have a slit about 15cm from the bottom, and you can button them up to make them like pants. The waist can be tightened with a drawstring. There are pockets on both sides of the waist. The size is M-L. Please understand that these are amateur measurements, amateur inspection, and home storage. Length: Approximately 120cm Width: Approximately 49cm Shoulder width: Approximately 56cm Sleeve length: Approximately 47cm Sleeve Length: Long Sleeve
