Fit Model


Measure around you chest at the fullest point of bust. Make sure measuring tape is relaxed and not tight. Please wear unpadded bra while measuring. Find you bust measurement above and pair with cup size to find your size.


Bend to one side to find your natural indentation in torso. This is your natural waist. Run the tape around your natural waistline, keep tape parallel to the floor and one finger in between body and tape for a more comfortable fit.


Measure around the fullest part of hips and bottom (approximately 7”-9” below waistline), keeping tape parallel to the floor.
