60s Lace Overlay Dress

Lots of scalloped lace trim this lovely ivory maxi dress. Could be a wedding dress? Rhinestone decorative buttons hide snap closure underneath. Hook & eye and pale yellow ribbon at empire waist. Stiffer lining, could be taffeta? Issues: needs snaps replaced (they are loose); yellowing of lace near hem; faint stains on ribbon (see last 2 pics). Could use a trip to the cleaners Norman Sacks, Inc., tag size 13, NO STRETCH! 19" armpit to armpit, 14.75" waist (empire waist), 54" length from shoulder.
