Vintage Diane Von Furstenberg Dress

Vintage Diane Von Furstenberg Dress. 80s. Beautiful button detail and waist peplum and belt. Shoulder pads. Poly/rayon hand wash fabric. Appears to be in excellent vintage condition. Only noticeable flaws or stain is the right armpit has some staining. (See pic) Size in not legible. I’m guessing around an 8-10 modern. Bust is about 20.5” across. Waist is about 16” across, hip is free, length is about 49”, shoulder to shoulder is about 18”, sleeve length is about 24”
