40C Bra Size

What is a 40C bra?

The letter in your bra size, aka your cup size, indicates how much larger your bust measures compared to your band. A C cup, for instance, means your bust measurement exceeds your underbust by approximately 3 inches.

Your band size is the numeric component of your bra size, such as the ""38"" in 38C, and corresponds to the circumference around your ribcage directly beneath your breasts. Because the band delivers the majority of a bra's support rather than the straps, selecting the correct band size is essential for genuine comfort and security.

Key bra features for 40C bra size

For a 40C bra size, you’ll find a wide range of styles that complement your natural shape while offering balanced support. If you want to enhance your shape or create more cleavage, opt for bras with structured foam cups or light padding.

These add definition without overwhelming your frame. A C cup generally benefits from medium to firm support, so you can comfortably explore both underwire and wireless options depending on your needs.

For a [insert band and cup size] bra size, we recommend skipping the bralette and opting for a wireless bra with bonded or molded support. Wireless bra styles offer lightweight and flexible support, plus additional smoothing and shaping benefits that a bralette can't provide.

For those in larger band sizes, opt for bras featuring wider wings and a contouring back design to smooth the sides and minimize any bulges for a clean silhouette.

Ideal fit for a C cup bra

For someone with a C cup, the ideal bra fit emphasizes structured support, smooth shaping, and secure lift. The cups should comfortably contain your bust without any gaping or spillage, creating a naturally rounded silhouette.

The band should do most of the supporting. It should feel firm and stable around your ribcage, but never tight or restrictive (you should still be able to fit two fingers underneath).

The cups should sit flush against your chest, fully encasing your breast tissue without wrinkles or overflow at the top or sides. The center gore (the middle part of the bra) should rest flat against your sternum, ensuring proper separation and support.

For C cups, look for well-anchored straps and cups with moderate coverage to balance lift and comfort throughout the day.
