HOW TO MEASURE
Use a tailor’s measuring tape to measure. You can also use a long piece of yarn or something similar and then measure the length with a ruler.
Measure your full bust (A) naked, or if you have sloped breasts or breasts that lay low over the underbust measurement, wear a soft bralette that doesn’t add volume but lifts them. We want a measurement of all the tissue, not just a part of it, so that as a result we don’t get a cup that’s too small. Place the measuring tape at the apex of your breast and be careful not to squeeze or compress the breast tissue.
Make sure the measuring tape is always parallel to the floor and not higher or lower in the back, except when measuring the high bust.
A- fullest part of the bust
B- ribcage (underbust), just under the bust
C- narrowest point of the waist, above the navel
D- widest part of hips
E- fullest part of bum
F- high bust measurment, above breasts
