Embroidered Chinese shoes slippers flats vintage flowered black satin

Amazing black satin soft flats, raspberry lavender passionflower embroidery- no size marked, measuring 9.25 inches heel to toe. I’d guess a size 6, please compare to a shoe that fits you well. Piped hem, rubber sole. They appear never to have been worn; clean canvas interiors. Bit of glue marks at the underside of one toe (not visible when worn), pin point stain on one flower when inspected, and a few marks on the sole but no wear. Bundle to save!
