I can't rate this dress highly enough. I ordered in a size 16 even though I'm an 18. It fits beautifully with lots of room across the back if needed. I have a large bust but didn't need a bra with this dress. It held me in securely and as its lined around the bust there was nothing to indicate I wasn't wearing a bra. Such a flattering shape, I felt like a size 10. Flattened my tum, skimmed over my hips and enhanced my bust. Stunning dress and will definitely be ordering in different designs.
