Vintage black sequin sleeveless blouse

This beautiful tank top is adorned with black sequins in an intricate pattern. The back has a zipper that runs the full length of the shirt. Partially lined. According to the vintage shop that I got it from, it was handmade in the 1950s. I couldn't resist buying it but I've never worn it (I'm not a sequin person), so I'm passing it on. It would be great for New Year's Eve or another semi-formal party! It's in great vintage condition with some minor loose threads. See photos for details and measurements. It fits me comfortably and I wear a size 8 or 10 top.
