Finding Your Underbust Measurement
-
Wear a non-padded bra that fits you well.
-
Stand up straight and wrap a tape measure around your ribcage, just under your bust.
-
Make sure the tape measure is straight and parallel to the ground.
-
Ensure the tape is snug but not tight, leaving the ability to fit a finger between the tape and your skin.

Finding Your Bust Measurement

Wear a non-padded bra that fits you well.
-
Stand up straight and wrap a tape measure around the fullest part of your bust, making sure that the tape measure is straight and parallel to the ground.

The tape should be snug but not tight, and you should be able to fit a finger between the tape and your skin.

Take note of the measurement in.
