1950s Alix of Miami green floral party dress with built-in bra & crinoline

Immaculate 1950s green floral party dress with built-in bra (!!!) and built-in crinoline. Sweetheart neckline. Wide straps. Pale green and yellow floral polished cotton. A marvel of engineering with amazing origami-like bodice, green contrast tuck on center front skirt, and side bow on full skirt. Label reads "Alix of Miami: Florida's First Name in American Fashion." This is a 1950s size 12, much smaller than a modern size 12: 18" armpit to armpit, measured flat. 13" waist, measured flat. Hips free. 40" shoulder to hem. 15" shoulder to waist. 15 1/2 metal zipper operates smoothly. Perfect condition, just needs a light steam after you unwrap it. Alix of Miami was known for "beautiful cocktail and dinner dresses with a tropical edge" (Vintage Fashion Guild). Happy to answer any questions!
