TL, DR: Would it be strange to wear my mother's wedding dress to my rehearsal dinner? Rehearsal, with dinner right afterwards, is being held at the venue the day before the wedding with just close family and the bridal party.
The long story (with pictures):
My mother brought out her wedding dress for me to try on almost as soon as I got engaged. I tried it on for a laugh and, suprisingly, it fit like it had been tailored to my body. The material doesn't stretch at all but every dimension is a perfect fit and has room to move comfortably.
My comment to her was, "Mom, it's really beautiful but HOLY SHOULDER PADS!" (She was married in 1991 so I shouldn't have been surprised)


This is what I am talking about... It is especially noticeable because I am petite.
She laughed too and said I didn't have to wear it at all if I didn't want to, but it might be one less dress to buy if I wore it to a shower or the rehearsal dinner.
I am considering removing the shoulder pads or replacing them with much thinner ones. Here is a side-by-side after removing the pad from one shoulder.

1) Any thoughts about the shoulders?
2) Should I even be considering wearing this dress to the rehearsal dinner? Would that be weird?
Thanks in advance!
