Laundry Long Black Dress. Cut out ribbon back with bow. Back slit. Size 12

Sensational long Black Dress. Made by Laundry. Very striking and elegant. The back is gorgeous with the ribbon cut out and bow. Has slit at back. Zipper on one side. Size says 12 but I find the t fits small - lore like a 6 or an 8. No stretch. Ptp 18.5. Length 57” Beautiful for an occasion. Little black bow at the back has a loose stitch otherwise in great condition. (Ref 101)
