Vintage 1986-87 ala carte California lace prom dress with bead detailing

Very good condition. This was my aunt’s prom dress in 1986. The photo is her in it in 1986. Shoulder pads. Zipper on side. The lining underneath is a light peach color. No content or size tag. I would say a vintage size 9. Probably a size 4-6 today. Armpit to armpit is 18 inches. Total length is 46 inches. Waist across front is 15 inches. Widest spot at hips across front is 18 inches.
