Nip Tuck Swim Sizing Guide

Bust Measurement

Due to our styles having different cup sizes, we have allowed for multiple measurements on the bust. Please refer to the measurement based on the cup size of your chosen style. As you can see, we have two measurements for your bust size depending on cup size. These cup sizes vary from a B Cup Bust, C Cup Bust, D Cup Bust, DD Cup Bust, E Cup Bust, F Cup Bust, and G Cup Bust, and will align with your standard bra cup size. As demonstrated in the picture above, make sure you have your tape straight across your back and you have measured the largest size of your bust.

Underbust Measurement

The underbust measurement is important in swimwear to ensure the underbust elastic is secured tightly and comfortably, this is especially important on a bikini set. This measurement is to be done at the point underneath your bust line and the circumference measured straight across the body.


Waist Measurement

The waist measurement is the smallest part of your torso, traditionally this would be directly between your bust and your hip however all women are different. Again, this measurement is to be done with a straight line circumference.

Hip Measurement

The hip measurement is the largest part of your body. This is not to be confused with where your hip line sits. If you find the largest part of your body, generally over your behind, this will give you an accurate measurement.
