Did you know that over 80% of women in the UK aren't wearing the right bra size?

Maddening, right?

Here is our "Find your fit" guide to help you measure your bra size and ensure you're getting the right one for you.

#1 Make sure you are using a soft, non-stretch, tape measure - this will give you the most accurate measurement.

#2 Have a pen and paper (and possibly a calculator) handy to note down your measurements as you go. There is a bit of arithmetic required between the underbust and cup measurements - they obviously wouldn't make it easy for us!

#3 It's easier (and more accurate) if you do the measuring over an existing everyday bra - ideally a non-padded one - with soft cups.

#4 Measure yourself in front of a long mirror (or your phone with the front-facing camera on). We recommend this because you can see whether the tape measure is sitting level all of the way around.

Step 1: Your band size

Making sure that you are looking at the inches side of your tape measure. Loop it around your ribcage directly under where your boobs are (where your underwiring would sit in a regular bra).

The tape measure should be level all of the way around. With the start of the tape measure sitting just below your sternum.

The number displayed is your band size.

Bra sizing is done in even numbers (don't ask us why). So, if you are between sizes then we would recommend adding 1 inch to the measurement when you note it down on your piece of paper.

Step 2: Your cup size

Next move the tape measure up to around your ribcage at the fullest part of your bust (roughly about where your nipples are).

Make sure that it is just resting on your chest and level all of the way around. There shouldn't be any of it that is cutting into you.

Again, looking at the inches side. Take a note of the number, we'll need it to work out your cup size using the table below.

Step 3: Calculating your bra size

Now that you've got both our underbust and cup measurements, subtract your underbust number from your cup number - this value will help you work out your cup size using the universal sizing table to the right.

So, for example if your underbust measurement is 32 inches and your cup measurement is 41 inches. 41 - 32 = 9in, so you are a 32G.

Our limitless bras run true to size, however some people can feel that the underband runs a little large. So if you are between sizes, we'd suggest going with a smaller underband size.

Fearless bra sizing

Our fearless bra offers a medium impact fit so runs slightly larger, if you would prefer a more compressive fit then we would suggest sizing down in the cup size and the underband.

T-shirt sizing

Our cropped t-shirts are a more relaxed fit. If you would prefer a tighter fit, we suggest ordering the size down.
