I love this bathing suit! I'm 5 1/2 months pregnant and I bought it for my babymoon next month. It fits well right now and the material is stretchy so I'll still have room to grow. One of the things I love about it is the length! I'm feeling a little self conscious about my butt right now and the skirt covers everything! I'm 5'3, 175 lb and got the 12-14. I recommend sticking to your normal size.
