Elegant LIV sheer black button-front top

Sheer black LIV top with hidden front button placket. Sleeveless with a seam around armhole with a raw edge trim which does not ravel. No fabric tag, but I would guess silk or high quality polyester or a combination of the two. The high neckline has 5 single layer waterfall type ruffles (also raw edge) that end around waistline with about an inch of ruching on either side. See the close ups for detail as it is hard to describe but really pretty. It has only been worn a few times and is in excellent condition. Although the closeup looks grey, the blouse is very dark black.
