Plus Size Amazon Swimwear Try-on! 1 - got a 2X and it runs comfy - it's a little small on the chest. 2 - love this so much runs true to size I got it in the 2X - as a 42DD I cannot size down on top from here so if unsure size up. 3 - I got the size 18 and the top is a little small and started rolling up so I suggest you size up. 4- yellow I got a 2X it runs true. 5 - I sized up to a 20 in this suit and I probably could have gotten my regular size. 6 - 2X in this coverup runs true but has no stretch. #LTKcurves
