Find your right bra size

1. Measure underbust circumference


Preparation: Wear a well-fitting, non-padded bra. Ensure it is neither too tight nor too loose but fits comfortably. Do not wear clothing over the bra to achieve accurate results.

Positioning: Stand upright and relaxed. Ensure your upper body is straight, and your arms are hanging by your sides.

Measurement: Take a flexible measuring tape and place it horizontally around your body just below your breasts. The tape should be parallel to the floor and fit snugly without digging in. It should be tight enough to stay in place but not so tight that it feels uncomfortable.

Reading the result: : Check in a mirror to ensure the measuring tape sits evenly and is not twisted. If you are alone and don’t have a mirror, try to keep the tape as straight as possible and use your fingers to feel if it is positioned evenly. Once the tape is correctly placed, read the measurement where the two ends meet.

Recording the measurement: Write down the measured value in centimeters. This is your underbust circumference. By following these steps carefully, you can measure your underbust circumference accurately on your own.

2. Measuring Bust Circumference


Measurement: Take a flexible measuring tape and place it horizontally around the fullest part of your bust, usually over the nipples. Ensure the tape is parallel to the floor and not pulled too tight. It should fit snugly without digging into your skin.

Reading the Result: Check in a mirror to ensure the measuring tape sits evenly and is not twisted. Make sure it runs across the widest part of your bust. Once the tape is correctly positioned, read the measurement where the two ends meet.

Recording the Measurement: Write down the measured value in centimeters. This is your bust circumference.
