BUST. Place one end of the tape measure at the fullest part of your bust and wrap it around your body to get the measurement, keeping the tape parallel to the floor.

---

UNDER BUST. Wrap tape so that it rests just under your bust, where your bra band would sit (just next to your ribs).

---

ARM. Wrap the measuring tape around the fullest part of your arm (around biceps part).

While during all measurements ensure that the tape is consistently level and that you are not wrapping the tape to tightly.
