R & M Richards Woman 1X (?) Jacket Top Black Sequin Gold Designs

Our mother wore this sequened jacket top on an Alaskan cruise in 2010 ( see last photos). Baded on the measurements, I think it is a 1X, but it could be 2X. She always cut tags out of her tops, so I used Google lenses to get further details. The stretchy polyester, nylon, and spandex fabric with sequins is lightweight. It has been machine washed inside out in a laundry bag, but line dried. The tank is lined and attached to the jacket. The approximate measurements are 24" across the chest, 17" sleeve inseam, 5" sleeve width, and 25" from the back neckline to the hemline.
