I ordered the 14-16, I am closer to a 16 though. It can be a bit complicated getting into the top due to the straps but it is easy to get into, I was quite surprised there is plenty of room for larger busted ladies. I'm 5ft tall so there is plenty of length for taller people and the under pants are a decent size also. I have put photos of me in just the top because I don't like to show my body, I know the straps aren't completely straight but that can be done just needs to be twisted back into proper position. Also very comfortable to wear.
