Vintage sparkling sleeveless tunic

This is a treasure! There are no tags, only the tag in the neckline. It says 38. I measured pit to pit is 21”. The length from pit to bottom hem is also 21”. The bottom is 29” across. There are seams for the bust that are hard to see. It’s pretty sheer with the lining inside the tunic. The zipper works great. It is very sparkly and pretty old. But in great shape!! ✌🏼
