I would go a size up on the bust. I'm a 32-34 bust and so I ordered a size 6 thinking it would be fine. The dress actually measured 30 under the bust and 34 around the fullest part of the breast. The size chart stated 34 and 1/2 inch for a size 6. So it barely fits and is a bit uncomfortable around the armpits. If it was just a 1/2 inch bigger it would have been a perfect fitting dress. It seems to be nice quality though with the stitching and the material.
