Only 3 because it is not even close true to size. Sooo cute. In the right size fits all the right places. However I would recommend not sizing up but twice. 5'2 118lb (very petite) but 36DDD. I could barely get pull the sleeves over my arms. Maybe if you're smaller chested it would fit better up top. Idk. But the material is thick and very tight. Again would look awesome in the right size. Please don't buy into anyone saying only 1 size up. I am VERY small and a SM in this materiel would still be too small. Good Luck When back in stock I will buy an M.
