How to find your best fit
1. Begin with your usual underwear size.
2. Refer to fitting comments on the product page for specific advice on each style, as well as product reviews from the RAQ pack.
3. Refer to the measurement table as a last resort, as measurements are intended as a rough guide and may not be suitable for everybody.
If in doubt, shop your normal underwear size and enjoy free exchanges for up to 60 days.
How to measure
Waist
Measure at the top of your hip bone and bottom of your ribs.
Hips
Measure at the widest part of your hips, making sure the tape is flat and horizontal.
There are several sizes available when shopping for bras and bra-sized swimwear. If we do not stock your true bra size or if we are sold out of your size, you can find a sister size below.
What's a sister size?
A "sister size" is a size that is different to your true bra size, but is still likely to fit you. The band will be bigger or smaller, but the cup capacity will remain the same.
You have two options, depending on whether you have room to go down in the band, or if you go up in the band:
1. Increase the band, and decrease the cup.
2. Decrease the band, and increase the cup.
Note: Both of these options will have a similar fit in the cup, despite the cup labels changing.
For example, if your true AU size is 12E/F, you can try 10FF/G or 14D/DD.
You can use our sister size chart below to quickly find your sister size. Following a diagonal line upwards, sister sizes are reflected in the same shade of pink.
For example, 8GG/H, 10FF/G, 12E/F and 14D/DD.
Note: Sizes in pink and purple are within our current size range.
Sizes in gray are outside our size range but have a sister size available. For example, if you are a 6HH/I, you may want to try an 8GG/H for a close fit.
A US sister size chart is on its way. For now, please convert your US size to AU to use this chart.
