What's the name of the dresses that are short in the front but long in the back?

I'm trying to look for dresses for my Sweet 16, and I really want a dress thats short in the front but it has like a long skirt back. I heard that they're called mullet dresses, but when I try to look on dress websites, nothing comes up. It would really help if I knew the real name or some websites that sell these kinds of dresses. Thanks so much ! :)
