Black, Gold, bronze sequins silk fancy blouse

Smoke-free home. This was my mother's. Has two side slits. Shoulder pads that can be removed. My mother used to go to dances at the senior center. You can hand wash this. I listed a few of her fun tops. Across the bust it 20in, but they're stretch in the material that will get it to 22" across. From shoulder to hem it's approximately 30" stretchy around the waist, about the same measurements as the bust. I'm thinking this is an extra large. But she cut out the tags!
