8DD Bra Size – Find Your Perfect Fit
What is a Size 8DD Bra?
A size 8DD bra is the perfect size for those with a smaller band and a fuller bust. In Australian bra sizing, the "8" refers to the band size, which is the measurement around your ribcage, just under the bust. The "DD" indicates the cup volume, offering extra room for those with more bust fullness.
To break it down:
- Band Size (8): Equivalent to a 70 band in EU sizing, it suits a snug ribcage measurement of around 68–72 cm.
- Cup Size (DD): Designed for fuller busts, providing superior support and structure.
This size is ideal for petite frames with a larger cup size, ensuring comfort, lift, and confidence.
