80s Party Dress Pink & Black Vintage

Sleeve shoulder to end about 17" Shoulder to shoulder about 17" Drop waist about 23" across front Shoulder to bottom edge about 43" Under arm to under arm about 23" across front Shoulder to bottom of pink trim overhang about 21 1/2" Pink belted area about 3" of pink hangover black. Plus size vintage 80's dress has black flowers and skirt. Pink top and drop waist tie. There are white squares throughout in a sponge pattern. Washed and clean. Has pin mark on left shoulder. Believe was stored with a pin in it in the closet. Right shoulder has a stitch mark shown in pictures. I'm not sure why? Both are pictured for details. I have detailed measurements as the size tag is missing. Her closet spanded from size 4 to 26, and some petites, so I can guess maybe size 16 to a 20. This drop waist shape fits a variety of sizes easy. However, if you need a fun 1980s dress for a party, you can alter as needed.
