Check out this convertible long prom dress by Jessica Angel that is two styles in one. Made in the USA, this gorgeous dress can be styled as a long halter formal dress with a deep v-neck bodice when the shoulder straps are tied into a bow at the back of the neck. In misses and plus sizes, this changeable long evening gown can get a strappy look with the same shoulder straps crossing over the open back. The long skirt opens in a side slit before flowing into a small train to complete the look of this convertible long prom dress that is a feast for the eyes no matter which style you choose.
