How to measure your body correctly

It's best to measure in just your underwear or tight-fitting clothing.

01

Chest

Run the measuring tape horizontally around the fullest point of your chest.

02

Underbust

Measure directly below your bust. This measurement helps with sports bras.

03

Waist

Measure the narrowest point of your torso without pulling in your stomach.

04

Hips

Measure horizontally around the fullest point of your hips and butt.

05

Inseam

Measure from the crotch straight down the inside of your leg to the floor.
