Roberta black Grecian one shoulder mini dress L

Very good condition, worn once. The under bust was altered to fit me ( 16.5”) but it can be reversed to approx. 18.5”. There is a flaw very hard to see (last two pics). Under bust is a transparent lace with sequin detail. The long sash is in two pieces so it can be tied or left hanging. Rufles and shell are like a “tulle “ fabric but more resistant. Grecian one shoulder. Upper part of the dress has Elastic on the back and rubber tape on the front. Size large. Color: black. 100% polyester. H
