Here is the size chart for selecting the Watery Katsu Short-Sleeved Rashguard for Kids. To find the right size, consider your child's height and the length of the rashguard.
If you find yourself between two sizes, choose the one that is closest or based on your preferred fit. If you want a snug fit, opt for the smaller size. Conversely, select the larger size if you prefer a looser fit.
