8B Bras – Delicate Structure, Confident Comfort
Looking for a bra that fits a smaller bust and petite band size without compromising comfort or style? Our 8B bras are crafted for women with narrow frames and modest curves. These bras offer tailored comfort, soft contouring, and breathable support – perfect for everyday wear. Whether you want light padding, a seamless finish, or a touch of lace, every 8B style we stock is designed for shape, simplicity, and all-day ease.
Understanding the 8B Bra Size
The 8B bra size combines a small band size (63–67 cm underbust) with moderate cup volume. The B cup refers to the difference in inches between the underbust and bust measurements – approximately 5 cm. It’s a balanced fit that offers structure without bulk, especially for petite body sizes.
It’s important to know that cup size isn’t universal – a 10A and 8B have similar letters but different proportions. Understanding bra sizing and Australian bra sizes ensures you get the right support and comfort every time.

How to Measure for an 8B Bra
All you need is a soft tape measure and a few minutes to get your body measurements right:
- Band size: Wrap the tape snugly around your ribcage, just under the bust (typically 63–67 cm).
- Bust measurement: Measure around the fullest part of your bust – keeping the tape level and parallel to the floor.
A small difference (around 5 cm) between bust and band measurements usually indicates a B cup. For extra support, explore our Size Guide or visit us in-store for a professional bra fitting with one of our expert team members.
