22I Bra Size - Support, Style & Confidence
Understanding the 22I Bra Size
The 22I bra size is specially designed for women with a larger band size and full cup volume. In Australian sizing, the "22" refers to the band size, which fits a rib cage measurement of approximately 107–112 cm under the bust. The "I" cup indicates a generous cup size—around a 9-inch difference between the band and bust measurements. This combination offers full coverage and support, making it perfect for large breasted women seeking a firm fit that doesn’t compromise comfort or style.

How to Measure Your Bra Size
To find your perfect fit, grab a soft tape measure and follow this guide:
- Band Size: Measure around your rib cage, just under your bust. Keep the tape snug but not tight and round to the nearest even number.
- Bust Measurement: Measure around the fullest part of your bust while wearing a non-padded bra.
- Cup Size: Subtract your band size from your bust measurement. Each inch difference typically represents one cup size (e.g. a 9-inch difference usually corresponds to an I cup in AU sizing).

Sister Sizes & Alternatives
Sometimes a sister size is the secret to getting that flawless feel. Sister sizes work because they maintain the same cup volume while adjusting the band size, which means you can still get a supportive and comfortable fit even if your usual size isn't available.
