Well, this is just lovely. Would make for a darling non-traditional wedding dress.
There is no fabric content label, but I would absolutely say it is silk shantung.
“Cold shoulder style – lace hangs off the shoulder with straps over the shoulders.
There is light pleating at the waist and bust darts.
Shoulder sleeves are organza – which is in good shape (organza usually shreds) – and covered in corded lace.
There is a center back lapped metal zipper.
It still has it’s original belt – the buckle is not great, but could it be changed easily.
