I'm glad I ordered the 4 as well as the 2 For some reason it was really tight right around my rib cage. The rest fit nicely. The waist and hips were loose on me and hid any little buldges or rolls without spanx or hose. I wore 4" heels and the dress was still too long in the regular size, I ended up having to carry it most of the night. But got lots of compliments and matched the jellyfish perfectly. (affair was hosted at the Monterey Bay aquarium.
