Designer "Eileen" Frock tag, with 20-1/2 marked size, but this is a vintage size, and NOT a modern size 20-1/2. VIntage sizes run smaller. Measures 20 inches across bust pit to pit, 15 across waist. Has side pockets. Classic white buttons from neckline to hem. Closer to a modern 14. Important Information: I don't accept returns, so please be sure of your measurements. Lay a dress that fits you well on a flat surface and measure armpit to armpit, waist, hips. I want you to be happy with your purchase! Also, my small town's post office is open limited hours 5 days a week and closed on Saturday, so please allow 3 days' handling. I try to ship the same day I receive the order, but this is not always possible. Happy shopping!
