This swimsuit is perfect!!! I'm an 18/20 and ordered the 4x for US 18 and it fits perfect. The suit is so flattering for plus size women! First thing I did was remove the cup pads because they always look weird. The shorts underneath and the dress aren't attached to each other until you get to the bust area which makes it easy to pull on some leggings and wear it as a tunic before/after swimming. The legs holes on the shorts do not have any elastic so beware of water slides or high activity use, you may give someone a free show lol. I feel so confident and pretty in this swimsuit, I almost want to get another pattern lol.
