Rose gold sequin top size small

Rose gold top. Small sequins, exposed zipper in back. Fully lined, not with uncomfortable polyester fabric, but something else (I don't know what and no fabric content tag, but I can tell you it won't make you sweat as much as some polyester linings). Only worn once. Now, I know the tag reads a size 10, but I wear a small (usually a 0 or 2), and I felt fine wearing this. Measurements below Bust: 16.5" (has some stretch) Length: 21" Black blazer sold separately.
