White Crochet Lace Satin Top, Very Unique, M Medium

This shirt has no brand or size tag. The material is like satin in that it has no stretch to it, and it has a beautiful sheen to it. The neckline, long sleeves, and bottom hem are a croched lace material. It measures approximately 19" across the chest from armpit to armpit. Please compare to a piece you own that fits well to ensure proper fit. There's a tiny spot pictured in the last photo. It is located right above the 8 on the ruler in the second to last photo. May come out in the wash; I have not tried. It appears to have been worn a time or two, but is in EUC excellent used condition otherwise. I have deeply discounted due to the spot. Please note that although we are a very clean household, I do smoke and have one lovely Calico cat who is beyond spoiled. :) Please feel free to ask any questions!
