I'm 32b-26-36, straight and slim, and the 0 fits like a glove. it's a nice change from all these loose, billowy (sometimes sack or tent like) dresses. if you are busty or have a broad rib cage, you'll need to size up for sure. the slip is fitted and im wondering if it will stay put. love all the colors in this dress - navy was better for me, the white washed me out and was just underwhelming. the band of lace hits high on my waist at a spot that is flattering and slimming which doesn't happen of
