The “b” in bra size stands for the cup size of the bra. Cup sizes are determined by taking two measurements – the bust measurement and the band measurement. The “b” cup is typically meant for women with a bust measurement that is 2 inches larger than their band measurement. This means that if your band measurement is 34 inches and your bust measurement is 36 inches, you would typically wear a “b” cup size.
Many people mistakenly believe that the letter in their bra size corresponds to how large or small their breasts are. In reality, the letter represents the difference between your bust and band measurements, not the actual size of your breasts. Understanding this can help eliminate any misconceptions about what certain cup sizes mean and allow you to focus on finding a bra that fits properly based on accurate measurements.
A less-known fact about bra sizing is that different brands may have slight variations in how they design their bras, which can affect how they fit. Knowing this can be useful when shopping for bras, as it may require trying on different brands or styles to find one that fits perfectly. I recommend considering trying on multiple brands and styles to see what works best for you based on these variations.
So now that you know what the “b” means in your bra size, let’s get you measured accurately so we can find some beautiful bras that fit like a dream.
