Vintage 1960s Dress with Belt, Blue with Yellow Polka Dots, Summer

Darling vintage 1960s dress in robins egg blue with yellow polka dots. Has a matching belt! Sleeveless, metal zipper up the back. I'd say in the smaller to medium size range but do see measurements below. No label. Looks and feels like cotton to me Excellent vintage condition. Has one pinhead sized hole on the skirt and I did spot some faint pindot marks near one shoulder. Measurements taken with dress laid flat. Doubled at bust, waist and hip. Armpit to armpit across bust: 36" Waist: 32" Belt has no holes but measures 30.5" from end to where the buckle connects Hips: free to about 40" Shoulder to waist: approx 14.5" Shoulder to bottom hem: 35" Please note: These are vintage, preworn and/or preloved items. I do my best to list any issues, but signs of wear should be expected. Please feel free to contact me with any questions. I'm truly happy to help in any way possible and I'm always up for a chat.
