Homecoming/prom dress navy/dark blue size 3, 2 piece set

This beautiful homecoming/prom dress is a size 3 in the color navy/dark blue. It has beautiful back straps that has embroidered flowers with sparkles everywhere in the front, on the back straps, and down the front of the dress. This is a 2 piece set. On the tag it says it is a size 3 but I have no option to select size 3 so I had to put size 4
