Beautiful dress, but it's too big.  I very much wear a size 14, but this dress in a size 14 was hanging on me.  There was a lot of extra fabric around the hips.  I'm more blessed on top than on the bottom, but for somewhere where the opposite is true, it would work well.
If I can't find anything else, I might go get it professionally tailored.  The dress wasn't that expensive so I could justify the costs.
