Vintage 1970s plum wine velveteen 2-pc suit dress

Great two-piece dress suit, comprised of a skirt and matching longer-line vest. The skirt has pockets and is button closure (no zip). The vest has a single button closure at waist, and belt loops. I’ve styled it wish a casual belt for one picture. Beautiful plum wine coloured soft material. Silky and velvet-like. Sort of a cross between velveteen and ultra suede. Very 1970s. No tags at all. Likely polyester. GUC. No issues. Skirt waist is approximately 12.5” when buttoned and laid flat. S.
