My mom wants to wear my grandma's wedding dress skirt to my wedding?
So this is complicated and weird, but I'm restoring and modifying my Grandma's wedding dress in the photos for my wedding. I was planning on removing the skirt and using the bodice(the skirt is italian silk, it's super heavy and long, and I would just prefer a skirt that maxi length and flowy that can detatch.
My grandma gifted me the dress and is fully on board. But my mom has been campaigning that I should give her the skirt from the dress so *she* can wear it to my wedding.
From what I can understand, she wants to keep the bustle but make the train shorter, and keep the skirt floor length.
She keeps telling me she'll wear a colorful top and it won't be all white, but my fiance is convinced that she is deliberately trying to look bridal on our wedding day. I really don't know, and I can't tell if it's appropriate.
For further context, my mom and dad eloped, and every time we talk about the wedding she is very insistant that details should look like what she planned for herself, and she is constantly bringing up how sad she is that she never got her dream wedding. My fiance thinks that this is the reason she wants to dress like a bride, but I still don't know and I think it's possible she could just genuinely want to honor my grandma.
Any insight from someone not involved in this situation would be appreciated!
Edit: Just by the way, my dad passed a few years ago so she won't get a chance for a renewal- thank you for all the comments! I appreciate the outside opinions TONS
Edit 2: Thank you all for the advice! It's good to know how this comes off to other people, I'll be talking to my mom and seeing if we can talk her down to something a bit less extravagent. Also, for people saying I should preserve the whole dress, I really wish I could, but this dress is 67 years old and was stored deeply incorrectly. The skirt took the brunt of the fall. It has lots of water damage and stains, as well as a plethora of small holes from moths and just, time. The bodice fared so much better than the skirt, and while there are parts of the skirt that can be salvaged, the result all of the seamstresses I've consulted have described would be straight down in the front with a bustle in the back, or a sort of circle skirt look with the very stiff, very thick fabric. That may be some people's cup of tea, but I'd much rather have a simple and flowy in a complimentary cream frabic. I like the idea people have presented of an overskirt that can be taken off for the reception, but I need to be able to move and I'm not about that big booty bustle life.
