Here is the size chart for selecting the Watery Salmon Glide wetsuit for women. The measurements are taken with the suit lying flat and not stretched. The wetsuit will give slightly during use and in the water, adapting to your body while swimming. Choose your size based on the measurements you are closest to.
If you find yourself between two sizes, choose the one where you match the most measurements. However, the most important measurements are generally the chest and height (ankle to shoulder).
A wetsuit should not be too loose, so if it creates many air pockets or “bags” around the suit, it is too large for you.
