In order to get the most accurate measurement possible it is recommended that you have an additional person available to help you. It is important that all measurements be taken WITH a bra on and your hands straight down by your sides. I recommend that you use a soft tape measure. These can be purchased at very little cost in the sewing section of any store and at most craft stores. Please make sure that the tape measure is snug against your body during the measurements and is parallel to the ground at all times.
Please use the image above in order to see more clearly where each measurement should be taken.
Measurement 1: Upper Bust
Measurement 2: Full Bust – This is the fullest part of your breast.
Measurement 3: Rib Cage – It is important that you first take a breath and let it out. Take your measurement BEFORE the next breath is taken.
