Vintage 1960s (?) Champagne Beaded & Sequined Back Zip Sleeveless Top Medium

Stunning sleeveless dress blouse with ornate champagne colored beading and sequins throughout. Full zip can be worn in the back or the front. Fully lined. Made in Hong Kong No fabric details. Size large. I am listing as a medium, as this does not measure like a modern large. Approximate measurements below. Please review carefully to determine your fit. 19” across pit to pit 19” long In excellent condition. Bottom part of zip is slightly off (see pics) but still zips up & issue is not noticeable to me. There are some small stains on the inside lining. Otherwise, again, the outside looks great. This is a well constructed piece!
