Ivory wedding dress with golden lace. Size 42 (XL-XXL) Never been worn

This (vintage) wedding dress of my mom’s has never been worn before. It has some stunning lace cutouts, with a zip and buttons. It sits fitted around the bust area, and flows down the rest of the body. It is too big for my mom in the photos since she has lost a lot of weight, so we pinned it back. It should fit someone who wears a size XXL and can fit an XL as well.
