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.

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.
If you have questions regarding your size, please send us an email for your free consultation: enquires@aiyanaswims.com
Measure your ribcage in inches keeping the tape measure parallel to the floor.
Keep the measure snug but not tight.
If you find an uneven measurement, round up to the next even number. This is your band size.
2) Step 2- Bust
Wearing a non padded bra, measure the fullest part of your bust keeping the tape parallel to the floor.
Keep the tape snug to your body, making sure it doesn’t dig in.
Round up to a whole number.
Now subtract your band number from your bust number.
