BUST:

Wrap the measuring tape around the fullest part of your chest, at nipple level. Round to the nearest whole number. This will become your bust measurement. Keep the tape snug but not too tight.

TIP: You will get an accurate measurement if wearing a non-padded bra.

WAIST:

Wrap the measuring tape around your natural waistline, which is located above your bellybutton and is the narrowest part of your torso.

TIP: Stand up straight, exhale slowly and ensure the tape is not digging in.

HIP:

Wrap the measuring tape around the widest part of your hips, ensuring the tape is level and is over the fullest part of your buttocks. Tape should be snug but not digging on.

TIP: Stand up straight, place your feet together, toes facing forward.
