What's your Basewear Top size?
This isn't your average sports bra! Use the chart below to figure out the perfect basewear size.
What's your Basewear Bottoms size?
Every body is unique. Follow the steps below to measure your perfect fit.

Measure Your Hips
Use measuring tape to wrap around your hips, just over your hip bone. Make sure to shed your current undies and don your birthday suit for the most accurate measurement. Remember to keep the tape parallel with the ground, and measure with a relaxed abdomen (don't try to suck anything in!). Write down your Hip Measurement to use in the next steps.
Handy Tip: If you don't have measuring tape you can use a piece of string, and measure it against a straight ruler.

Measure Your Buns
Next, wrap your measuring tape around your buns at the point where your peaches are their most plump. Make sure the tape remains parallel to the ground. Write down your Butt Measurement to use in the next steps.
Do A Little Math
Here's the easiest homework you've ever aced! Plug the measurements you just took into the equation below to get your Basewear Bottoms recommendation.
(Hip Measurement + Butt Measurement) ÷ 2 = Bottoms Measurement
Plug your Bottoms Measurement into the chart above to figure out your size! Good job you.
