Wedding dress - help with dating, also a mending question

Hello All,

I've got a vintage wedding dress that I believe is likely from the 70's, but was hoping someone might have some more insight- not only in regard to dating, but perhaps a designer/label? The only label inside is from I. Magnin. The lace and ball fringe appear to be cotton, it has full circle bell wrist flounces, and a plastic zipper if that helps with dating.

Also- this dress is in overall very good condition- with the exception of a couple of small hols in the netting of the skirt, see pic. I really don't know how to fix this- is there really any way that would not be even more noticeable than these little holes?

 

Bumping. Really just curious as to if there's any trick to mending holes like that in such a way that wouldn't be super noticeable.

 

I think the holes will show more if you try to mend them. They appear to be very small.
