I not sure that it would be noticeable when buttoned, but they could easily be replaced by a seamstress. The front yoke does have some pulls in the netting, again this is not noticeable. I noticed that a small area in the seam of the waistline needs reinforcing. The gown has a few minor rubs, otherwise it's great. It does need to be cleaned.
Beading looks to be all intacted.
The gown comes with a cathedral length veil. The veil is edged with lace which matches the underskirt of the gown. The headpiece is unusual in that it frames the face in a half circle. There are some holes in the veil, and I don't think it is useable as is, but it could be used as a pattern or an example of the type of veil which was originally worn with this gown. The veil and the lace in the gown have a blue tinge to them.
