Black maxi dress with cut out back

Gorgeous black maxi dress with lace trim and cut out design on back. Full tulle overlay. Worn once for a few hours as bridesmaid in wedding. Received so many compliments! Been in a garment bag since. Like new. Labeled on the site as a prom dress but could be worn to any formal event. I’m 5’5” and wore 3.5 inch heels
