Finding Your Perfect Bra Fit
Finding the right bra can feel tricky—but it doesn’t have to be. With a few simple checks, you can make sure your bra gives you the support, comfort, and confidence you deserve.
-
1. Start with the Band – It Does Most of the Work
The band provides about 80% of your bra’s support, so getting this part right is key.
How it should fit:
- Snug but comfy — it should sit straight around your body.
- If it rides up your back, it’s too big.
- You should only be able to pull it about two inches away from your body.
💡 Tip: If your straps are digging in or your bust feels unsupported, your band is probably too loose.
- Snug but comfy — it should sit straight around your body.

2. Check the Cups – No Spilling or Gaping
Your cups should hold all your breast tissue comfortably, without cutting in or leaving gaps.
What to look for:
- Spilling over the top or sides? Try a bigger cup size.
- Wrinkling or gaping? The cup might be too large.
💡 Tip: It’s totally normal for one breast to be slightly bigger than the other — always fit to the larger side.
- Spilling over the top or sides? Try a bigger cup size.

3. Move Around – Your Bra Should Move With You
Once it looks good in the mirror, do a quick comfort test.
Lift your arms, twist, or bend forward — your bra should stay in place and feel supportive no matter how you move.
What Are Sister Sizes?
Sister sizes are bra sizes that have the same cup volume but different band sizes.
They’re super helpful if you find that your usual size feels a bit too tight or too loose in the band — you can move up or down in the band size and adjust the cup size to keep the same fit in the cups.

How Sister Sizing Works
- If you go up a band size, go down a cup size to keep the same cup volume.
- If you go down a band size, go up a cup size to keep the same cup volume.
💡 For example:
- If your usual size is 34FF/G, your sister sizes are 32 GG/H(tighter band) and 36E/F (looser band).
- The cups will feel the same — only the band fit changes.
- If you go up a band size, go down a cup size to keep the same cup volume.

Why Sister Sizes Matter
- Perfect if your band feels too snug or too loose but your cups fit well.
- Great for brands with limited size ranges — it helps you find your best fit even if your exact size isn’t available.
- Ideal for different fabrics and styles — a compressive sports bra might need a bigger band, while a stretchy style might need a smaller one.
- Perfect if your band feels too snug or too loose but your cups fit well.

Understanding Dual Cup Sizing
Our bras are dual cup sized (for example, 32FF/G) because they’re made from supportive, stretchy, non-wired fabrics that adapt to your body.
Unlike traditional wired bras, which fit one exact cup size, our designs are flexible — giving you the right amount of lift and comfort across a range of cup sizes.
