I'm 5'4, approximately 140lbs, 36B wears size 6-8 and I got this in M and it fits perfectly. Tight at first but very comfortable. My waist is defined better when I wear it and it smooths out the undesirable bulges. I just wish they made one where the back is not as high because if I wear a dress that has a lower back like where your bra strap is, this bodysuit will shows since it sits approximately 5 inches above your bra line. Otherwise I love everything about it and plan to buy the nude color as well so I can have a whole set.
