Let’s find your under band measurement.

• You'll need a pen and paper, a tape measure in inches, and your best fitting bra.
• We are going to use your bra, with the tape measure to identify your size. We are ‘true to size’, which means comparable to other brands.
• First, we need to understand the size of your rib cage (your frame).
• Measure around your ribcage under your bust and pull the tape measure very firm and tight. Breath out and relax to get the smallest measurement.
• The tape measure needs to be tight, but the bra wont feel tight. Please trust this, and pull the tape measure tight, to get your smallest measurement and write it down in inches.

Looking at this grid below, Which ribcage measurement are you?

You could be on the cusp of two sizes. If this is you, please opt for the smaller under band.

• On the grid we have added 4 inches on the even 5 inches to the odd to get the bra band size.
• Write down your bra band size.

What you need to know about cups sizes!

• Did you know bra cups have Sister Sizes?
• This means the same cup volume is used across band sizes . Please see the grid below, all of the same colour diagonal boxes have identical cup volume just a different band size.

All of the white boxes from 42A to 28FF have identical cup volume just a different band size. (Hard to believe we know, but it’s true!)

• When you increase the band size, in order to keep the same cup volume, the letter goes down.
• When you need a smaller band, to keep the same cup volume, you go up a letter.

Let’s park this for now, we will come back to it

Let’s look at the bra you have been wearing

Do you fill the cup and is it smooth?

Or is the cup slightly small, are you spilling over the top? If so, do you need to go up one cup Size? If it’s a C then a D might be better.
Or is your cup roomy inside? Do you have any gaps or wrinkles in the cup or is the top cup empty? If so… you need to reduce the cup. If you are wearing a F then a E might be better.

Now, Lets combine the under band and cup

• Find your previous believed bra size.
• We always start with the band size first before calculating the cup.
• To calculate your size follow the example below.

38D previous size Move diagonally to your new band size. Or stay put if the band size is correct. Then… If your cup is big (in your existing bra) move down a cup. If your cup is small (in your existing bra) move up a cup. Write down your size.

• If your cup size doesn’t need changing, you will always stay on the same diagonal colour and move up or down your band.
• If you are changing the cup size you will move horizontally and change the colour of the diagonal.
