So Im 55-56 147 and got  This dress in a medium. And it fits good. But its not a fitted dress on me with this size. Im a 34DD andbthe chest area fits perfect. If it wasn't for That i would have actually gotten it a small. I have some room in the waist and hip area. Thought about actually getting it taken in a bit aonit can be a more fitted Fit. But i can get away with it as is. But it definitely does not run small. Its also right below my knees. I got the black and red floral one Ill post a pic when i actually wear it out
