International sizing chart
Aiyana currently offers a wide range of sizes, primarily based on UK measurements. Please use our international size conversion chart below to help find your best fit.
Our pro tip: Start with our easy-to-use band size conversion chart, followed by the cup size chart. Finally, review the bikini brief conversion chart to complete your sizing.
If we do not carry your exact top size, you can use our alternative sister size chart below to find the closest fit likely to suit you best.
Sister CHART for bikini tops
If we do not stock your exact size, you can use our alternative sister size chart below. A sister size is a different bra size that offers a similar fit to your true size.
In the chart below, sizes shown in the same colour group are considered equivalent fits. As a general rule, if you go down a band size, you should go up a cup size — and vice versa.
For example, while we currently do not stock a true 38 DD/E, this size has an equivalent fit to our 36 F/FF.
The chart below represents UK sizing and so we ask our international community to reference the international sizing chart too.
| 30 DD/E | 32 DD/E | 34 DD/E | 36 DD/E | 38 DD/E |
| 30 F/FF | 32 F/FF | 34 F/FF | 36 F/FF | 38 F/FF |
| 30 G/GG | 32 G/GG | 34 G/GG | 36 G/GG | 38 G/GG |
