Sheer black & purple tie-dye blouse

Sleeveless blouse is a button-up sheer, paneled, tunic-length beauty. It is about a size 6, between a SM and a MED. It has no tags whatsoever and has been in storage for a bit, lol, so maybe from the 90s? I tried doing a search for something similar, but no luck. Rare item. Pit to pit measures ~18.5" flat Guessing 100% polyester
