Here is the size chart for choosing the Watery bathrobe for women. For this bathrobe, the starting point is your length, chest circumference, and sleeve length when you need to find your correct size.
If you are unlucky and are between two sizes, choose the one that is either closest to your measurements or according to your preferred fit. Additionally, you need to decide which fit you prefer. For a tight fit, choose the smaller of the two sizes, conversely, choose the larger of the two sizes if you want a looser fit.
