Vintage Oleg Cassini sequin blouse size small fits size medium

Vintage Oleg Cassini sequin blouse circa 1980s Silver and black sequin with flower pattern on front & back Silver accent beads at neck, sleeves, waist trim Hook & eye closure at sleeves and back of neck Sewn in shoulder pads Size small but as it’s an oversized style could fit medium I’ve looked it over and don’t see any bald spots in the sequin Last photo shows a loose thread with one loose sequin but great overall shape. I purchased this second hand and have not dry cleaned it
