The Importance of Proper Bra Sizing
(and how to make sure yours is right)

by Sonia Dane

Welcome to my comprehensive guide on the importance of proper bra-sizing and how you can make sure yours is right! I understand the frustration that comes with uncomfortable, ill-fitting bras and the negative impact it can have on your daily life. That’s why I'm here to help you find your perfect fit and achieve optimal comfort and support.

Why Proper Bra Sizing is Essential

Did you know that a vast majority of women wear the wrong bra size? In fact, studies show that up to 80% of women are wearing the wrong size bra! This can lead to a plethora of issues such as back pain, neck pain, and even headaches. Improperly fitting bras can also cause discomfort, chafing, and irritation, leading to decreased confidence and overall quality of life.

A well-fitting bra, on the other hand, provides support for your breasts, improves posture, and distributes weight evenly across your back and shoulders. It can also enhance your natural shape, provide a smoother silhouette, and boost your self-confidence.

How to Determine Your Correct Bra Size

Finding your correct bra size can be a challenge, but with the right tools and guidance, it’s possible. Here’s how to do it:

  1. Measure Yourself

The first step to finding your correct bra size is to measure yourself. You’ll need a soft measuring tape and a mirror to ensure accuracy.

Start by measuring around your ribcage, just below your breasts, making sure the tape is snug but not too tight. Round up to the nearest whole number if the measurement is not exact. This measurement is your band size.

Next, measure around the fullest part of your bust, making sure the tape is parallel to the ground and not too tight. Round up to the nearest whole number if the measurement is not exact. This measurement is your cup size.

  1. Use a Bra Size Calculator

Once you have your band and cup size measurements, use a bra size calculator, or the chart below, to determine your correct size. Keep in mind that different brands may have slight variations in sizing, so it’s essential to try on bras from different brands to find your perfect fit.

All size chart measurements are in inches, unless otherwise noted.

  1. Try on Different Styles

Not all bra styles are created equal, and what works for one person may not work for another. It’s essential to try on different styles such as underwire, wireless, push-up, or sports bras to find the right fit and level of support for your needs.  This is the fun part after all!  So bring a partner and make a day of it - and find out what makes your breasts look their best and makes you feel your sexiest.

  1. Adjust the Straps and Band

Even with the correct bra size, you may need to adjust the straps and band to ensure optimal comfort and support. The band should fit snugly around your ribcage, and the straps should be adjusted so they don’t dig into your shoulders but provide enough support to lift your breasts.

Benefits of Wearing the Right Bra Size

Wearing the right bra size has numerous benefits, including:

  1. Improved Posture

A well-fitting bra can help improve your posture by providing support to your back and shoulders. It can also prevent slouching and hunching, which can lead to long-term spine issues.

  1. Enhanced Comfort

Wearing a bra that fits correctly can eliminate discomfort and pain caused by poorly fitting bras. You’ll be able to move freely without feeling constricted or irritated.

  1. Boosted Self-Confidence

Wearing a bra that fits you well can boost your self-confidence and improve your body image. The right bra size and style can even enhance the size of your breasts, making them appear fuller firmer and sexier, and can add deep cleavage when you want to have an alluring decolletage. You’ll feel more comfortable, secure, confident, and sexy, allowing you to focus on the tasks at hand rather than being distracted by discomfort.

  1. Improved Breast Health

A well-fitting bra can prevent sagging and help maintain the shape of your breasts. It can also reduce the risk of breast pain and discomfort caused by unsupported or poorly supported breasts. Although I must add that I have also seen some doctors say that going braless can not only give you that feeling of liberating comfort, but can also give you improved muscle tone and breast shape, better circulation, increased comfort over time, and better breast skin health. This is a personal choice for you of course. But I say you should be confident no matter what your bra choice is. The most important factor to a woman's beauty, I say, is her confidence and pride in whatever she see's as her own best assets.

Sister-Sizes: What Are They?

Now that we've covered the basics of proper bra sizing, let's talk about sister sizes. If you're like many women, you may have experienced the frustration of trying to find a bra that fits perfectly. Even when you know your size, not every bra style or brand will fit the same way. That's where the concept of sister sizes comes in.

Sister sizes are bras that have different band sizes but the same cup volume. This means that if you find a bra in your size but it doesn't quite fit, you may be able to find a sister size that will work just as well.

To understand sister sizes, it's helpful to know how bra sizes are determined. Bra sizes are made up of two measurements: the band size and the cup size. The band size is the measurement around your ribcage just below your breasts. The cup size is the difference between your band size and the measurement around the fullest part of your breasts.

For example, if your band size is 34 inches and the measurement around the fullest part of your breasts is 38 inches, your cup size would be a D. This would make your bra size a 34D.

However, as I mentioned earlier, not all bras will fit the same way even in your exact size. That's where sister sizes come in. Sister sizes have the same cup volume as your usual size but a different band size.

For example, if you typically wear a 34C bra, your sister sizes would be a 32D and a 36B. These bras will have the same cup volume as your usual size but a different band size.

Understanding sister sizes can be incredibly helpful when shopping for bras. If you find a bra that you love but it doesn't come in your exact size, you can try a sister size that will still give you the same cup volume. This can expand your options and help you find the perfect fit.

However, it's important to note that sister sizes aren't perfect substitutes for your actual bra size. The fit may vary depending on the brand and style of the bra. For example, if you try on a 36B bra and the band feels too loose, you may need to try a 34C instead.

When trying on sister sizes, it's important to pay attention to how the band fits. If the band feels too loose or too tight, you may need to adjust the cup size accordingly. For example, if you try on a 36B bra and the band feels too loose, you may need to try a 34C instead.

It's also important to remember that different styles of bras, such as plunge, demi-cup, or full-coverage bras, may fit differently even in the same size or sister size. It's always a good idea to try on different styles and sizes to find the one that fits your body the best.

Understanding sister sizes can be incredibly helpful when shopping for bras. It allows you to expand your options and find the perfect fit, even if the exact size you need isn't available. Remember to pay attention to how the band fits and try on different styles to find the one that fits your body the best. With this knowledge, you can feel confident and comfortable in your own skin, no matter what size or style you choose.

Different Types of Bras: Lined vs. Unlined

When it comes to choosing the right bra, it's important to consider the type of bra you need for the occasion. Lined bras are great for everyday wear, as they provide added coverage and shape to your bust. They are also perfect for when you don't want your nipples to be visible through your clothing. Unlined bras, on the other hand, are great for when you want a natural look or when you're wearing a sheer top and feel like showing off a bit. They don't provide as much coverage, but they can be very comfortable and sexy.

Final Thoughts

At the end of the day, it's important to remember that every woman's body is unique and beautiful. Whether you have a small bust or a large one, it's important to find a bra that fits you properly and makes you feel confident. Don't be afraid to try on different sizes and styles, and always choose a bra that makes you feel comfortable and supported. And when you feel like it, don't be afraid to go braless, and just leave that bra at home, and feel the sensations of your breasts being free.

Remember, it's not just about finding the right size, but also finding the right style and type of bra for your needs. Lined bras provide extra coverage and support, which may be ideal for women who want to avoid visible nipples or for those who have a larger bust size. On the other hand, unlined bras offer a more natural look and feel, and may be preferred by women who want to embrace their curves and feel sexy in their lingerie.

When it comes to sister sizes, keep in mind that while they may offer a suitable alternative if your exact size isn't available, they are not always a perfect substitute. It's important to try on different sizes and styles to see what works best for your body and your preferences. And if you are experiencing weight fluctuations or changes in your breast size, it's a good idea to get fitted regularly to ensure that your bras are still providing the right support and comfort.

In conclusion, finding the right bra size is crucial for your comfort, health, and confidence. By following the steps outlined above, including measuring yourself correctly, considering sister sizes, and exploring different styles, you can ensure that you are wearing a bra that fits you perfectly and makes you feel your best. Don't be afraid to experiment with different looks and embrace your unique body shape – after all, there is no one-size-fits-all when it comes to women's bodies! And yours is beautiful!
