International sizing chart

Aiyana’s swimwear uses UK under band and cup sizes. They are made with the same expertise as bras. We currently offer cup sized swimwear in 16 sizes and are looking to expand our sizing offer! The table below displays our UK and international sizing conversions. Our pro tip is to start off with our easy- to use band size conversion chart followed by the cup chart.

If we do not stock your true size, you can find your alternative sister size. A sister size is a size that is different to your true bra size but is likely to fit you. The general rule is to go down in your band size and go up in a cup size or visa versa. For example, a size 36 F/FF is equivalent to our size 34 G/GG and 38 DD/E.

Alternative Sister Size

30 DD/E 32 DD/E 34 DD/E 36 DD/E
30 F/FF 32 F/FF 34 F/FF 36 F/FF
30 G/GG 32 G/GG 34 G/GG 36 F/FF

You can use our sister size chart to easily find your equivalent sister UK sizing. If needed, please use the international conversion chart to convert to your local sizing.

Finally, once you’ve found your perfect cup-sized top, we can help you find your bottom size using the conversion chart above.
