Venus Wedding Dress with Train Lace Pearl size 6 or 7

My mother's wedding dress with a detachable train and zip up back. She thinks she was a size 7, more photos available I can send you (it only let me put in 10). She was 5'6" and 130lbs with small breasts. Smoke free home. It's been stored in a dress bag and a box after being professionally dry cleaned in 2000. Only worn once.
