Vintage 1970’s ivory lace tiered wedding prom summer long maxi dress EVC size S

Gorgeous lace dress has satin ribbon straps, and tiers of lace. The tags have been cut out, but I can tell that one was a union tag and they are all paper. The top straps are not adjustable, but the waist has elastic, as does the bust line and the elastic is still fully functional. Top elastic measures approximately 12 inches and stretches to 14 and 15 comfortably. Waist measures approximately 10 inches and stretches to 15 and 16 and more comfortably. Each tier has satin ribbon and floral lace. Dress is fully lined and from the top elastic to the measures approximately 51 inches. Liner is a nylon satin and has a tear which is not noticeable when worn. There are a few stains at the lower end of the dress that I will try to launder and remove.
