Don't size down if you're busty
I took everyone's advice and purchased a size small instead if medium.  i wish i had gotten my usual size as the neckline and bodice is very tight.  i'm top heavy with a wide rib cage and 36dd's.   other than that, the skirt of this mango hued beauty is large loose and flowing which i can see why people suggest sizing down.  i think my fit problem would be solved if petite was available.
