G Cup Bras

The G cup bra, a size we've truly thought through at Sans Complexe Paris

Finding a G cup bra that combines support, comfort and style shouldn't be an uphill battle. At Sans Complexe Paris, we design our styles for a very full bust, with deep cups that naturally follow your shape instead of flattening it.

Our collection includes underwired G cup bras as well as wire-free styles, in a wide range of band sizes (from 40 to 48, depending on the style) and colours, from classic black or white to bolder shades. Several of our ranges, such as Arum or Narcisse, even go up to J cup, so you never have to switch brands as your bust changes.

How to measure and check your G cup correctly

Before choosing your underwired G cup bra or a wire-free style, it helps to be sure of your size. Measure your band size just under your bust, then your bust measurement across the fullest part: the difference between the two determines your cup size. A difference of around 8 inches usually points to a G cup.

Remember to re-measure regularly, especially after pregnancy, a change in weight, or hormonal changes: cup size shifts more often than you'd think. For a precise fit, check our full bra size guide, with all our band and cup size conversions.

Which bra shape works best for a G cup?

Not every bra shape suits a deep cup equally well. Some constructions are built to distribute the weight of the bust so straps don't dig in and the bra doesn't shift throughout the day: a wider back, wide, adjustable straps for firm support, and multi-panel cups all make a real difference to comfort.

Balconette or underwired: our recommendations for your bust

The underwired bra remains the most versatile shape for a G cup: it fully encases the bust without compressing it, for natural everyday support. It's the shape most represented in our selection.

A balconette bra in a G cup also suits a very full bust well, provided you choose a style with sturdy underwiring and cups designed for fuller figures: that's exactly the case with our Thilda style, which combines a plunging shape with structured support. If you're after extra support for everyday wear, look for a style with a wide, stable back, which distributes the weight of the bust better than a standard back. Our underwired styles with a U-back, like Suzan, follow this same logic of reinforced support.

Still torn between shapes? Our guide Which bra to choose for a fuller bust covers every option in depth.

If you're after targeted support that streamlines your silhouette, our minimiser bra Perfect Curves, available in a G cup, redistributes the bust for the visual effect of one cup size smaller, without ever sacrificing comfort.

Style and comfort aren't mutually exclusive: our lace G cup styles

Having a very full bust doesn't mean giving up feminine lingerie. Our Suzan range, in lightweight floral lace, comes in a G cup and pairs a delicate finish with structured support thanks to its side boning and U-back. Our Thilda balconette style, in two-tone embroidery and tulle, brings a more sultry touch, without giving up the underwiring.
