Wedding dress Size 0

I’m 5”2, less than 100 Lb, cub size A. The dress was never altered and it fits perfect since it is a size 0. The front go a few more inches to the ground so it can fit from 5”2-5”5 perfectly (Depends on heels or if you like the front to cover the floor. The quality is surprisingly good! I just bought it from someone who wore it once, loved it but I just found out I am expecting a baby before the wedding date so this won’t work since it fits just right when I tried it on.
