Vintage formal dress

Vintage black dress from Flirtations by Alfred Angelo. Dress is form fitting and black with a floral print, and a little keyhole with a pearl/rhinestone embellishment in the front. Morticia Addams vibes! Purchased for a special occasion, so I’m ready to rotate it out. I am 5 feet tall even, and this hits a little above my ankles. Marked as a 9/10 but I call this a modern 2/4. Flat measurements: 14 inches across the waist, 17 inches armpit to armpit, and approximately 42 inches from top of armpit to the bottom of the dress. Slit in the back.
