You'll need a non padded bra and a tape measure. If you only have a ruler at your disposal, use a thick string or rope and measure that instead. Please the tape measure/rope under the bust to measure your size, preferably in cms. Take note that the tape measure should be level and you'll want to measure when its tightest.
Now, shift the tape measure up and measure the circumference of your busts. To do that solo, you'll want to wrap the tape measure around your back and bring the ends to the front of your bust. For this, again take it in cms and keep the tape measure loose.
Refer to the tables below and find the guide for Step 1 and Step 2 on the respective tables. The under bust measurements are on the top table, and you'll refer to the matrix in the same column in the cup table to find your On Bust Measurement, and that will give you the best gauge of what size you are.
Pro Tip: Simply walk into any lingerie store near you and get the store assistants to give you a proper measurement and that would work as well.
