Vintage Shapely Knits grape cluster applique top unsized M (?)

Semi sheer 80s white sleeveless top with gathered shoulders and fitted waistband. Appliqued with a cluster of grapes. Some wash wear present and some snagging of grape fabric. Garment is freshly laundered but there is a small area of yellowing on left shoulder and some red dye transfer from another item on inside and outside of waistband (very light on outside, barely shows up in final photo). Unsized, estimating an oversized fit on a size medium, as the waistband is quite stretchy. Please see measurements and ask for any additional information that will help ensure fit.
