prom dress help?

sooo.. prom is coming up soon (march) and I’m really excited but idk what type of dress to get. I’m really short (4’11) and skinny but I don’t have a box shape either if that makes sense. I really don’t want to wear a short dress but I don’t want my dress to look ridiculous on me. I was looking for a long rose gold glittery one with maybe a slit on it? idk some tips would be appreciated please!
