Solid Stretchable Shorts

Chest/Bust

Wrap the measuring tape around the fullest part of your bust.
To get the most accurate measurement, get a flexible plastic measuring tape and bring it around your torso to the fullest part of your breasts.
Position the tape directly over your nipples and relax your arms at your sides. If possible, get someone to help you take the measurement so you're able to keep your arms down.

Waist

Stand up straight and breathe normally.
Hold the end of the tape measure at your navel and circle it around your back to the front of your waist.
The measuring tape should be parallel to the floor and fit snugly around your torso without digging into your skin. Exhale and then check the measurement on the tape.
Your waist measurement will be at the place on the tape where the zero end meets the slack end of the tape measure.

Hips

Stand straight with your feet perfectly close to each other.
This accentuates your hips and will help you take a better, more accurate measurement of the full size of your hips. With your feet close, wrap the tape measure around the widest part of your hips to get the perfect measurement.
