Vintage JC Penny formal dress

Adorable mauve colored vintage JC Penny’s dress. Doesn’t have a size but I would estimate a modern day small. I’m general good vintage condition, no tears rips or noticeable stains. Is missing the top button in back, an easy fix. All vintage items have signs of wear, I do my best to inspect and point out any flaws. Feel free to ask any questions- thanks for looking!
