For a perfect fit – Cake Bras
A. Below-the-breasts measurement
This measurement is the diameter of your bust right under your breasts. Use a fabric measuring tape and place it right under your breasts. Make sure the measuring tape is laid horizontally across your back (look in a mirror or ask someone to help you). Ensure you don’t capture any of the breast tissue while measuring.
Write this measurement down and locate the corresponding bra band size in the chart below (the second column, using the French system):

First, measure your bust size, wearing a well fitting bra (preferably non-padded) and using a fabric measuring tape. Place it at the fullest part of your breasts. Ensure that that the tape is placed horizontally across your back (you might want to have someone help you or to check yourself in the mirror). Don’t pull the tape too snuggly, ensure that there's some wiggle room.
