I am a true size 16, and I ordered the 16/18 and it fit great, the bottoms were a bit big, so I am going to order the 14/16 bottoms as well. The picture of this suit does not do it justice. This suit is adorable, and I wore it with black bottoms as well, and it looked just as nice. I prefer to wear it as a Bandeau top and let the ties just dangle down the front. Very glad I bought this suit. The material is very soft.
