Finding The Perfect Fit: A Guide To Bra Sizing

Finding the perfect-fitting bra can be a daunting task for many women. The right bra size not only ensures comfort but also enhances your shape and boosts your confidence. However, with the vast array of bra sizes, styles, and brands available, it’s easy to feel overwhelmed. That’s why understanding bra sizing is crucial. In this detailed guide, we’ll go over everything you need to know about bra sizing, from how to measure yourself to how to spot common fitting problems. By the end of this article, you’ll have the knowledge to find the perfect fit and experience the comfort and support you deserve.

Understanding Bra Sizing

Bra sizing consists of two components: the band size and the cup size. While the cup size denotes the volume of the breasts, the band size refers to the numerical measurement around the torso, right below the bust. The most commonly used bra sizing system involves using a combination of letters and numbers, such as 34B or 36D. The number represents the band size, while the letter denotes the cup size. When exploring different brands for the perfect fit, it’s worth considering renowned options like Prima Donna Bras, known for their exceptional quality and diverse range of sizes.

Measuring Yourself Correctly

To find your accurate bra size, you must start by measuring yourself correctly. Grab a gentle measuring tape and proceed as follows:

  • Band Measurement: Stand straight and exhale to get the smallest possible measurement around your ribcage, just beneath the breasts. Round this number to the nearest whole inch. Add one inch to get your band size if the number is odd.
  • Cup Measurement: Wrap the measuring tape around the fullest part of your breasts, ensuring it is parallel to the floor. Make sure the tape is snug but not too tight round this number to the nearest whole inch.

Determining Your Bra Size

Now that you have your band and cup measurements, it’s time to determine your bra size. Use the following steps:

  • Find Your Band Size: Start with the band measurement you obtained earlier. If the measurement is 32 inches or below, add 4 inches. If it’s above 32 inches, add 2 inches. This will give you your band size.
  • Calculate Your Cup Size: Subtract your band measurement from your cup measurement. Each inch difference corresponds to a cup size. For example, if your band is 34 inches and your cup is 36 inches, the difference is 2 inches, indicating a B cup.

Common Fitting Issues And Solutions

Even with accurate measurements, fitting issues can still arise. Here are some common problems and their solutions:

  • Spillage: If your breasts are overflowing from the cups, your bra is too small. Try increasing the cup size.
  • Gaping Cups: If you notice empty spaces or wrinkles in the cups, your bra is too big. Consider going down a cup size.
  • Riding Up Or Digging In: If the back of your bra rides up or the straps dig into your shoulders, the band is likely too large. Opt for a smaller band size.
  • Underwire Digging: If the underwire is digging into your skin, it could be due to a cup size that is too small. Try a larger cup size.
  • Uneven Breasts: If your breasts are noticeably uneven, consider getting bras with removable padding or seek professional fitting advice.


Finding the right bra size is critical for comfort, support, and self-esteem. By understanding bra sizing and measuring yourself correctly, you can eliminate the frustration of ill-fitting bras. Remember that bra sizing may vary between brands and styles, so it’s crucial to try on bras to find the best fit. Be patient, and don’t be afraid to seek assistance from professional bra fitters if needed. A well-fitting bra can transform your daily experience, providing the support and comfort you deserve. Embrace the journey of finding the perfect fit, and enjoy the confidence that comes with it.
