Your preliminary size recommendation
How to measure your body correctly
It's best to measure in just your underwear or tight-fitting clothing.
Chest
Run the measuring tape horizontally around the fullest point of your chest.
Underbust
Measure directly below your bust. This measurement helps with sports bras.
Waist
Measure the narrowest point of your torso without pulling in your stomach.
Hips
Measure horizontally around the fullest point of your hips and butt.
Inseam
Measure from the crotch straight down the inside of your leg to the floor.
