Special Savings Other Ginza collection

I have a never worn wedding grown (except to try on after purchasing). It is a halter style, A line with a small/medium train. Dress size is 16, but street size is 10/12.There is bead work and embroidery throughout the dress... Very pretty! The pictures don't do any justice. I paid just over $700 for the dress and I am asking $350. It needs to be dry cleaned or steam ironed to straighten out because the dress has been stored in a sealed bag.
