I've been using this in my daily life, but I'm selling it now because I no longer use it. This is a versatile all-in-one piece, suitable for both formal and casual occasions! The waist is elastic, making it comfortable to wear. There was no size label, so I've listed it as free size. (I usually wear a size M, but I was able to wear this item without any issues.) ⚫︎Please only purchase if you understand that this item has been stored at home and is a used item.⚫︎
