Here is the size chart for choosing Watery Remington Women's Bikini Bottom. For this bikini bottom, hip measurement, leg opening, front size, and back size are used to find your correct size.
If you happen to be between two sizes, choose the one that is closest or based on your preferred fit. You need to assess which fit you want; for a tight fit, choose the smaller of the two sizes, and conversely, choose the larger of the two sizes if you prefer a looser fit.
