Our Size Guide
Amber London’s mission is to empower women of all body shapes by making swimwear that truly reflects the diversity of the female form. For that reason, fit became the nascence of our brand.
Our Tops are fitted by cup-size and not the conventional XS-XL scale, which assumes that small back sizes have a small bust and vice versa. We refer to sister group sizing of 1-6, where sizes are grouped based on the cup volume that they cover, for example if you are normally a UK 32DD then you should opt for size 4, this will also fit UK sizes 30E, 34D and 36C, which have the same cup volume. To work out your sister size, you can go up a cup size and down a back size and vice versa.
Please refer to the size chart below to work out your best Amber London size and if you have any questions, please reach out to us by emailing support@amberlondon.com
