I was really torn between sizes and sized down to an 8 (for reference, my waist is 28 inches, bust 34 & height 5 ft 2.5). I think if I'd gone with my usual size, it would have been too big in the shoulders & the bust (it fit perfectly in both places). The waist fits in the right place, although the dress is a smidge on the long side (but not long enough to warrant hemming it) and it does cling a little bit to my stomach, but not in a way it would stop me from wearing it.
I do have a qualm though, and that was that a little bit of the stitching in the waist had come loose, so I had to put a few stitches in.
Overall, it's a lovely dress in a stretchy but heavy fabric. And has huge pockets
