Shop Full Cup Bras
A full cup bra gives you complete coverage and all-day support, encapsulating the bust fully so there is no spilling out the front, sides or over the top. It is the style our fitters reach for most, because the deep cups, side support panels and underwire work together to lift, separate and hold a fuller bust securely. If your most common wish is simply to feel fully supported and not low cut, this is the collection for you.
The old idea that full coverage means a plain, matronly bra no longer holds. Across the range you will find everyday basics alongside prettier lace and detailed styles, all built for genuine support in true cup sizing through to LL. For a different shape our balconette bras and plunge bras sit alongside this collection, but for sheer coverage and security the full cup is hard to beat.
Why Shop Full Cup Bras at DeBra's
For over 25 years we have fitted Australian women across the full A to LL cup range, and the full cup is our go-to style in the fitting room. We stock it from the brands fuller busts trust, including Elomi, Fantasie, Goddess, PrimaDonna and Sculptresse, each built with the deeper cups and firm side support a larger bust needs.
Because full coverage only works when the band and cup are right, every order is backed by free fittings in store, by phone or over Zoom. If you are unsure of your size or shopping our plus size bras, a quick fitting will point you to the styles that hold and flatter best. Free shipping is included Australia-wide on orders over $150.
Full Coverage and Full Support
A full cup bra holds all of the breast tissue inside the cup, which is what stops the spillage and bulging that lower-cut styles can cause on a fuller bust. The underwire follows the natural breast line from under the arm into the centre, while side support panels stop tissue drifting toward your back, giving a smooth line under clothes.
Within the collection you can match the finish to how you want to wear it:
- Everyday styles in smooth fabric for invisible support under work and casual wear; our T-shirt bras give the same seamless finish.
- Lace and detailed styles for when you want pretty without losing coverage; see our lace bras.
- Wire-free full cup options for soft, all-day comfort when you would rather skip the underwire.
Finding Your Full Cup Fit
A full cup should contain the bust completely, with the underwire sitting flat against the ribcage, the centre lying flush, and no tissue escaping at the top or sides. If any of that is not happening, it usually means the cup or band is not quite right, which a fitting sorts out quickly.
Not sure where to start? Our fitters will help you find a full cup that supports and flatters at your exact size, whether you want reliable basics or something prettier. Browse the full range of bras online, or visit us in store and let us fit you properly.
Frequently Asked Questions
What is a full cup bra?
A full cup bra covers the whole bust with deeper cups, side support panels and, usually, an underwire, giving maximum coverage and support. It is the most secure, supportive everyday style, which is why it is the go-to for fuller busts who want to feel fully held.
Are full cup bras good for a fuller bust?
Yes. They encapsulate the bust fully so nothing spills out the front, sides or top, and the side support panels keep a smooth shape under clothes. For larger cups, a full cup is generally the most supportive and comfortable everyday choice.
What is the difference between a full cup and a balconette bra?
A full cup covers most of the breast for maximum coverage and support, while a balconette is cut lower and straighter across for lift and a rounded shape with less coverage. If security and a smooth line matter most to you, the full cup is the better pick.
Do full cup bras have to be underwired?
Most are wired for structure, but you will also find wire-free full cup styles that give soft support and full coverage without an underwire. Both can support a fuller bust well when the fit is right.
