Beautiful Vintage White Slip with Lace Matching Robe size Large

Beautiful Vintage White Slip with Matching Robe size Large Stunning set, from the late 60’s or early 70’s I believe. Is very long, midi/maxi length depending on height. Has some staining on both the slip and the robe - looks like it could be red wine, see photos of stains. Could potentially be cleaned to remove or have be less noticeable.
