I am 5'5' and 135-140 lbs and the size 10 is just about perfect with a pair of Spanx. The 12 would have been fine too, with the slightly looser look that the model wears. Mine is a more fitted style. If you are larger than a DD bra size, the top might be tricky.
I plan to wear to a wedding. I love it.
