Vintage Cocktail Dress

Beautiful, happy colors. Fully lined. No tags. Material is soft, shiny, and has satin feel to it. To be honest I can’t date the dress. Looks 50s but has a plastic zip (60’s?) None of this however takes away the loveliness of this dress. It has no pockets or belt loops. No flaws that I can see. Approximate measurements are taken while garment is flat. (See pictures) Bust 18” Waist 14” Hips 19”
