This is a Global Work one-piece dress. The size is L. The width under the armpits is 50 cm laid flat, shoulder width is 40 cm, sleeve length is 60 cm, and the center back length is 89 cm. All measurements are approximate due to being measured by a layman, so there may be slight errors. Please understand. The back has pleats. The back has lining on the inside, so it is not see-through. I am selling it because I have outgrown it. There are no scratches or stains, but I have worn it with affection, so please refrain from purchasing if you are sensitive to such things.
