Sister Sizing

Is your bra size missing? Find your sister size in the conversion chart below.

Sister size are bra sizes that fit the same, but have different size names to what you are used to. To find your sister size you either go one size up or down in your band size, and the opposite in your cup. For example, a 10B sister size is an 12A (up one in the band and down one in the cup) or an 8C (down one in the band, and up one in the cup). We've converted some popular sizes for you below. 

To find your sister size, find your bra size below and every other size in that row will be a suitable fit. 

 

Need help?

Step 1: What is your t shirt size?
For bralettes, we suggest starting your sizing with your T-shirt size first (across the top row), and then considering your cup size next (down the left column).

Step 2: What is your cup size?
If your cup size is substantially bigger than your T-shirt size, then we suggest you go up a size.

If your cup size is smaller and your under bust is broader, then we suggest sticking to your T-shirt size.

Step 3: Measure your under bust
Still having trouble? You can also measure your ribcage (under bust) to get a more accurate idea of the best fit around the body.

Still having trouble? Contact us and we'll be glad to assist.

Finding Your Cup Size

1. Measure around the largest part of your bust in inches

2. Measure around the ribcage underneath your bust in inches

3. Minus the difference from your bust to ribcage, and check against this chart:

Difference in Inches 0 1 2 3 4 5 6 7
Your Cup Size is: AA A B C D DD E, F G

Favourites!

I bought these in pink around a year ago and they are by far the most comfy undies I have worn, the lace is soft, the gusset is the right size (and doesn't look like pocket! small details count), everything about it. When I saw the new colours I had to get them!
