Mother-in-law

So my fiancé and I will be getting married at the end of June. A couple of months ago, His mother went on and on about her veil, and how she wanted me to wear it. Without looking at it, I stupidly told her that I would. After she gave it to me, I saw that It’s a VERY dated veil, with tulle sticking up, and it goes around the forehead with beading, etc. I even had it dry cleaned to make sure that that’s how it really was and not from storage. not my style at all. The way she made it sound, it was a regular veil.

Since then, I found a veil that I loved at a thrift store, and purchased. Since he knows her best, I asked my fiancé to tell his mom that I wouldn’t be wearing her veil, and he told me he would. I assumed it was over with.

The day before yesterday, my grandma texted me and said she wanted me to wear her veil. I told her that I would want to look at it first since I already had the one I had purchased. It matches my current veil and lace on my dress, and she told me to incorporate it however I wanted. I am thinking I might add it to my veil as a layer, or something, I haven’t decided yet. Yesterday, my grandma was talking to my future mother in law and mentioned how excited she was that I would be probably using her veil, and according to my grandma, my future mother in law said, “I thought she was wearing my veil?” I thought this was taken care of, and I don’t want to hurt her feelings... how do I tell her that I won’t be wearing her veil? Because now I need to be the one to say something since my fiancé didn’t when I asked him too.
