Eve of Milady wedding gown

This Eve of Milady wedding gown is such a beautiful timeless piece! I actually bought it for a Halloween costume as Iman with my husband as David Bowie. It has beautiful button details, lace trim, a bow, the volume of the skirt which is not too overwhelming, delicate train and sheer bodice with lining to cover the bust and stomach for modesty. More pics or measurements let me know. Asking $700 OBO - regular dress size 4, not sure the “wedding” size.
