GORGEOUS light Gray formal dress. Mother of bride or groom. Perfect condition

Size 18 mother of bride or groom dress. Obviously to tight (see pic of back 🤦🏻‍♀️) I bought and am reposhing. I couldn’t even get it zipped. I was soooo disappointed! I will add more pics if requested. These were sent to me. This is a beautiful, very forgiving, figure flattering style (if you can get it zipped 🤦🏻‍♀️). I started my diet to late for this beauty 🤷🏻‍♀️ was only worn once by original owner. She had it dry cleaned. It is a very light Gray. Pit to pit is approx 21”, waist approx 18” across, hips approx 23”. There is not stretch.
