C-Cup Bras

Frequently Asked Questions

• What is a C cup?

  A C cup refers to a specific bra cup size that represents the difference between the band measurement (the circumference of the torso just beneath the bust) and the fullest part of the bust. Specifically, the cup size corresponds to a 3-inch difference between these two measurements. For example, if the band size is 34 inches and the bust measures 37 inches, the individual would wear a 34C bra. It’s important to note that cup sizes are relative to the band size, meaning a 32C will hold less volume than a 36C. This makes the C cup a versatile size that suits many different shapes and proportions.

• How to measure for a C cup bra

  To measure for a C cup size, you’ll need two key measurements: your band size and your bust size. First, measure your band size by wrapping a soft measuring tape snugly around your ribcage, just below your bust, ensuring the tape is level. Round to the nearest whole number and add 4 inches if the number is even or 5 inches if it’s odd (e.g., 30 inches becomes 34). Next, measure your bust size by wrapping the tape around the fullest part of your chest, keeping it straight but not too tight. Subtract your band size from your bust size to determine your cup size. A 1-inch difference equals an A cup, 2 inches equals a B cup, and a 3-inch difference equals a C cup.

• How big Is a C cup bra?

  A C cup bra is often considered a medium-sized cup that offers a balanced combination of coverage, volume, and support. It represents a 3-inch difference between the band measurement and the fullest part of the bust. However, the actual cup size varies depending on the band size due to the concept of "sister sizing." This makes the C cup versatile, fitting women with different torso sizes and breast shapes. It provides a rounded, natural shape that works well under various styles of clothing, from fitted tops to dresses.

• What Is the Biggest C Cup Bra Size?

  The largest C cup bra size depends on the band measurement since cup volume increases with a larger band. For example, a 48C has significantly more cup volume than a 34C, even though both are technically a C cup. This variation occurs because the cup size must accommodate the proportional difference in breast volume as the band size grows.

• Which Is Bigger: B Cup or C Cup?

  A C cup is larger than a B cup because it represents a greater difference between the band and bust measurements. Specifically, a B cup corresponds to a 2-inch difference, while a C cup corresponds to a 3-inch difference. This means that the C cup offers more volume and coverage compared to a B cup, regardless of the band size. However, the relative increase in size will still depend on the band measurement; for instance, a 34C will be larger in cup volume than a 34B.
