Beautiful size 16 navy blue gown

Beautiful form gown. Worn once for a military ball. I think it just needs to be dry cleaned. It’s a size 16. I am only 5ft so it was altered for my height. I had room to wear heels and it still slightly hit the floor. Pictures don’t do it justice. I paid about $300 for it, not including alterations. It was purchased from Macy’s. The brand is JS Collections. It’s navy blue with a black sash.
