Medium (M): Fits C cup sizes, offering moderate-full coverage

How to take your measurements for the Perfect Fit
Using the image to the right as a visual reference, follow this simple guideline to determine your ideal size:
i). BUST - Wrap a measuring tape around the fullest part of your bust, ensuring the tape is level across your shoulder blades
ii). WAIST - Wrap the tape measure around your natural waistline, allowing it to sit comfortably loose for accurate measurement
iii). HIPS - Wrap the tape measure around the fullest part of your low hip, ensuring the tape sits level across the widest aspect of your backside
