Im 59 and very busty and 19 weeks pregnant and ordered and XL and its perfect! I could have been fine with a large at this point but I really wanted the oatmeal color. But the XL still fits nicely, doesnt hug, and is long which I need being tall and busty. Now Ill have some room to grow for later into my pregnancy with it! This is a steal considering how much maternity clothes are!! Only thing is I wish the tank came in a better color/size selection so I could buy them all!
