Vintage prom dress Y2K 90s long purple black sheet overlay formal gown

this for this years prom but the high neckline didn't work for us - loved the lace side cut outs and color though - size 5/6 and truly vintage with back Zipper closure - measures 15" across bust - 14" across waist - 20" across hips and a very long 54" from top of breast to bottom hem - dress is 3 layers - a neon pink tulle underneath for volume, satin iridescent purple and dark purple tulle with black velvet floral design THERE IS A RUN BY THE BOTTOM BACK ZIPPER- refer to last pic
