Bra cup sizes B and C differ in the amount of breast tissue they can accommodate. The main distinction lies in the depth and width of the cups, with size C being deeper and wider than size B to provide more coverage for larger breasts. In terms of volume, a B cup typically holds around 240-270 cubic centimeters of breast tissue, while a C cup can accommodate approximately 270-300 cubic centimeters.
It’s important to note that the band size also plays a crucial role in determining the difference between these cup sizes. For instance, a 32C bra will have smaller cups than a 36C bra due to the difference in band circumference. This means that while both sizes are designed for different volumes of breast tissue, they can look quite different when paired with varying band sizes.
A common misconception is that going up a single letter from B to C means only a slight increase in size. However, this is not entirely accurate as there is actually a significant jump in volume between these two cup sizes. The truth is that even one letter change can result in noticeable differences in fit and support.
A less-known fact about bra sizing is that it’s not uncommon for someone to wear multiple cup sizes depending on the style and brand of bras. This is because different manufacturers may have slightly different measurements for their cups, so finding the perfect fit may require trying on various sizes within your usual range. Knowing this can be useful as it allows you to be open-minded when shopping for bras and not restrict yourself to just one specific size.
Now that you understand how bra cup sizes B and C differ, I recommend taking some time to measure yourself using our fitting guide or asking our expert staff for assistance if you’re unsure about your current size. Once you have determined your correct measurements, try on different styles within those sizes to find what works best for you.
