Flat measurements: waist approximately 33cm, length approximately 87cm. The waist is elastic. There is a lining. The sleeves are lace and are see-through. The shop label at the neckline was cut off from the time of purchase. There was no size notation, but someone who usually wears a size M wore it, so I have listed it as a size M. Please understand that this is a used item and has been stored at home before purchasing.
