What is a BreaStep 1: Bust Measurementst Pump Flange?
To measure your bust size accurately, wrap a measuring tape around the fullest part of your breasts, across the nipple area. Hold both ends of the tape with one hand at the side of your breast, and use your other hand to gently press the tape between your breasts so it sits snugly against your chest. This will give you a more precise measurement of your bust.

Step 2: Underbust Measurement
To measure your underbust, wrap the measuring tape around your chest, just below your breasts. Make sure it goes around your back and under your armpits. Use a mirror to check that the tape is level and parallel to the floor. It should sit firmly against your body—snug, but without any fingers underneath the tape—for the most accurate measurement.

1–2 cm = AA cup
3–4 cm = A cup
5–6 cm = B cup
7–8 cm = C cup
9–10 cm = D cup
11–12 cm = DD cup
13–14 cm = E cup
15–16 cm = F cup
17–18 cm = FF cup
19–20 cm = G cup
For example, if your bust measures 95 cm and your underbust is 85 cm, the 10 cm difference means you’d be aD cupin Australian sizing.
