Great fit and feels great
Collected order today and it's just a normal swimming costume. I'm a size 10 but 25 weeks pregnant so needed bump room - have ended up buying size xl!
I'm 5'7", size 12 and 19 weeks pregnant and ordered a medium which fits really well. It seems there is lots of give in the rouched material around the middle for my bump to grow. There's an elastic panel under the bust which is comfortable and not too tight and is supportive enough for my growing bust, and the material doesnt pull down like some costumes! The only downside to this costume is the material is not as good and quick drying as more expensive costumes (like Zoggs or Speedo), but for the price I wouldnt have expected it to be.
