Getting the right bra size doesn’t have to feel complicated. At Berlei, we believe every woman deserves a bra that supports her body and her lifestyle. Taking a few simple measurements at home is the first step towards all-day comfort and confidence.
Your body naturally changes with time, weight fluctuations, hormonal changes, exercise, and even the natural ageing process can all affect your bra size. That’s why we recommend checking your size every six months.
Follow our step-by-step guide below:
Step 1: Measure Your Underband
Stand in front of a mirror and hold a soft measuring tape.
Wrap the tape firmly around your ribcage, directly underneath your bust.
Make sure the tape lies in a straight line across your back — not dipping down or riding up.
Pull it snug, but not so tight that it digs in. You should be able to take a deep breath comfortably.
Note the measurement in inches or centimetres. This is your band size.
Step 2: Measure Your Bust
Keeping the tape measure level, wrap it around the fullest part of your bust.
Ensure the tape is lying flat but not compressing your bust.
Take the measurement while standing straight and relaxed, ideally while wearing a non-padded bra.
Note down this number in the same unit of measurement you used for your band size.
Tip: Always measure while wearing a non-padded bra for the most accurate result.
