Underbust Example

Measure your underbust

Stand with your arms resting by your side and ideally get someone else to measure you around your body, directly below the bust. Make sure the tape is right under your breasts, is straight all the way around and is as tight as possible.

This is how the underband of the bra will fit, so the tape should be tight, but not uncomfortable. It's best to do this measurement while you're not wearing a bra, or you can do it wearing one, just be careful not to sit the tape over your bra or underwire.

This measurement is your UNDERBUST.

Underbust Example

Measure your overbust

Measure around the fullest part of your bust (usually over the nipple). This is best done while you're wearing a bra. Hold the tape gently so that the tape is resting lightly on your body. Make sure that the tape measure is straight across your back, and sits parallel to the floor.

This measurement is your OVERBUST.

The importance of a good fit

It's important to find a bra that is well constructed, and the right size for you. A bra that doesn't fit or is poorly made can cause shoulder, neck and back tension, sagging breasts, and uncomfortable bulges around your breasts and upper arms and even where it fits across your back. Eeek!

You can do your own measurements with or without a bra on. It's easier to get the underbust measurement if you have a friend to help.

Doing this will help you find the perfect bra fit for your body. Use the calculator above to find your bra size for Australian bras; now you are ready to shop from one of the many BERLEI bras in your size!
