50's Vintage Cocktail Dress

Beautifully constructed cocktail dress from the late 1950's. Immaculate condition. There is some wear on the belt, not damaged, can just tell it's been worn. Amazing chord work. Extra detail in the back creates a slight bustle. Satin has a sheen that changes with the light, see pics. There are flattering darts at bust. There is no liner. I would call it a size 4 with extra hip/booty. Measurements taken flat, as follows: Bust 35" Waist 27" Hip 40" Shoulder to waist 15" Skirt length 28.5"
