This is a very old knit two-piece set dating around 1940. I'm guessing it to be a size small to medium. There are some snags, like 4ish little holes, like 2. A couple of repairs, and discolorations that could possibly be washed out. The chest measures 36 inches laying flat and not stretched. This fabric is of course Very stretchy. The length of the top is 19 in. It has mother of pearl buttons that snap closed. The skirt ways has a pulled drawstring that is adjustable but the rough opening is 30 in. Some of the little loops that hold in the drawstring are broken. Like four maybe. The length is 29 to 30 in Long. There are some discolorations on the skirt but could be washed out possibly. I did not see any snags or holes in the skirt. Take picture one and two as the true color. This comes from a smoke-free home
