According to reviews, customers said to order up in size. They were saying it was super small. I wear about size 2x. I'm 5'3" 200lbs my chest being about 42D. I carry my weight in my stomach. I got the 5x and it is HUGE!!!! I probably should of gone with the 2x or 3x. I washed it and it did not shrink. Sigh... guess it will be a comfy lounge shirt. It's really cute, though!
