What Is My UK Bra Size?

Find Out With Our Bra Size Conversion Guide!

You’ve probably seen lots (and lots!) of bra size conversion charts and if you're confident your bra is fitting you well, the bra size conversion chart below will help you find your equivalent UK size to try. But, we understand that deciphering the bra alphabet can be confusing and a little overwhelming, especially since all lingerie brands fit slightly differently! So, we’re happy to say that we are here to help you find your feel-good fitting bra (7 days a week!). The best way to find your UK size is to speak to one of our friendly bra fitters, whether that’s over the phone, in one of our shops or via a virtual fitting we’d be more than happy to give you our advice on what size is best to try!

We are here to help 7 days a week!

Book a virtual fit

Our experienced fitters have always fitted by eye and without tape measures, using the bra you are currently wearing as a starting point, so they can guide you through the different sizes, styles and shapes and help you to find the best fit for you (all via a video call!).

WHAT TO DO IF YOUR BRA IS UNCOMFORTABLE

IF YOUR BRA IS UNCOMFORTABLE, PLEASE STOP WEARING IT AS SOON AS POSSIBLE AS IT COULD CAUSE INJURY.

We advise what we believe to be a good fit, but only you can know if your bra feels comfortable. If your bra is uncomfortable, please get in touch with us so we can help.
