HOW TO MEASURE

Band size

Measure around your ribcage, directly underneath the bust. Add 5 to this measurement to obtain your band size (i.e. 32, 34, 36). For example: ribcage measurement of 29" + 5 = 34" band size. If you get an odd number, round up or down depending on how you like your bra to fit.

Cup size

Measure loosely around the fullest point of your bust, then subtract your band size from this measurement. Each inch of difference will determine your cup size. For example: bust measurement of 36" - 34" band size = 1"or a B cup. A difference of 1" = A cup, 2" = B cup, 3" = C cup, and 4" = D cup.

How to measure without a ruler or tape measure?

If you don't have a ruler or tape measure handy, you can try to measure with a standard credit card, which has a width of 3 ⅜ inch or 8.56 cm and a height of 2 ⅛ inch or 5.4 cm.

If you do a lot of online apparel shopping, accurate body measurement using a tape measure is a must. The actual tape you choose doesn’t matter that much. This retractable one is very easy to use, and the fact it uses both CM and IN is extremely helpful.
