I wore this for my backyard Couple's Shower and it was perfect! There's no zipper, but the back of the bodice is stretchy so it fit like a glove. And because of the stretch I bet it would fit someone one size smaller or larger than me. I did not need to wear a bra with this dress because I felt comfortable in it and didn't need the extra support. I never had to worry about pulling up the top of the dress either...stayed right in place! The length of the skirt was comfortable and the pleating with underskirt give it just enough oomph underneath. Loved it!
