10G Bra Size Collection

Your Perfect Fit: Understanding the 10G Bra Size

Finding a bra that fits like a dream starts with knowing your true bra size. The 10G is a beautifully balanced size designed for curvy & full-bust women with a smaller underbust and generous bust projection. In Australian sizing, the number refers to the band size (your ribcage measurement), and the letter refers to the cup size (volume of the breast).

A 10G bra fits someone with a 10 band (around 70 cm underbust) and G cup. It's ideal for curvy women who need extra support without compromising on style. Whether you’re after everyday comfort, sports performance, or fuller bust lingerie, we’ve got a huge range that caters specifically to DD-G breasts.

International Size Equivalents

Understanding the bra size chart across different regions helps you shop confidently:

Region Size Equivalent
Australia (AU) 10G
UK 32G
US 32I (often labelled 32G in some brands)
EU 70I
France (FR) 85I

*Note: Always refer to our size chart for exact conversions.

Quick Sizing Guide: How to Measure

    All you need is a soft tape measure:

    1. Band Size: Wrap it snugly under your bust. Round to the nearest whole cm. If it reads 70 cm, you’re a size 10 band.
    2. Bust Measurement: Measure around the fullest part of your bust.
    3. Cup Size: Subtract the band from bust size. The difference determines your cup size.

    For extra guidance, visit our Fitting Guide or speak to our Expert Bra-fitting service team.

    Sister Sizes: Your Flexible Fit

    Can’t find your exact fit? Sister sizes give you more options:

    • 8H (tighter band)
    • 12F (looser band)

    They maintain the same cup volume, perfect for exploring different coverage bra options or adjusting fit in different brands.

    How do I know if I'm wearing the right bra size?
