DeLaru light Blue plus size gown with matching shawl size 20

Prom dress worn once and in storage for about 20 years. Beautiful light blue halter style gown. Beading along the neckline. Only alterations done were moving the buttons on the halter strap and adding a safety pin to keep them in place. Some light marks on strap from makeup. Beautiful dress still in great shape! I’d be more than glad to take any measurements you need.
