The Differences Between Plus Size Bra Sizing and Standard Sizing

When it comes to bra sizes, not all bras are created equal. The terminology related to bra sizes, especially when it comes to extended bra sizing, can be confusing if you're not familiar with it. Many women end up wearing the wrong bra size simply because they don't understand the differences between various sizing options. In this article, we will break down the distinctions between standard bra sizes, plus size bras, and full bust bras. By the end, you'll have a better understanding of which size is right for you and how to find the perfect fit. So let's dive in!


Understanding Standard Bra Sizes vs. Plus Size Bras

The primary difference between standard bra sizes and plus size bras lies in the band size. Standard size bras typically range from band size 30 to band size 38. These are the most commonly found sizes in many lingerie stores. On the other hand, plus size bras are designed for those with band sizes 40 and above. However, it's important to note that different brands and retailers may have their own definitions of plus size lingerie. To ensure you find the perfect fit, it's crucial to know your precise bra size. If you're uncertain about your band size, consider taking your measurements using a tape measure or visit a local lingerie shop for a professional bra fitting.

Differentiating Plus Size Bras from Full Bust Bras

Apart from plus size bras, there is another category of bras known as full bust lingerie. Full bust lingerie is specifically designed for those with cup sizes DD or larger. If you have larger breasts and wear a larger cup size, you likely fall into the full bust category. However, being considered plus size doesn't necessarily mean you need to wear a full bust bra. For instance, if you have a standard band size of 34 and a cup size of G, you would be considered full bust. Full bust bras are primarily defined by cup sizes.


It's important to understand that plus size bras and full bust bras can be mutually exclusive or overlap depending on the sizes. If you have a larger band size and a large cup size, you will likely need a plus size bra. However, it's also possible to wear a bra size that's considered just plus size (i.e., a large band size), just full bust (large cup size), or both. These concepts can intersect in certain sizes.


Additionally, it's worth noting that cup sizes are not consistent across different band sizes. For example, a bra size of 36F is equivalent in cup volume to 38DD and 34G when considering sister sizing. This means that individuals with different body types may wear the same cup size by volume, despite having different band sizes.


Understanding Full Bust Lingerie

When it comes to full bust lingerie, wearing a cup size of DD or larger can encompass a wide range of cup sizes, catering to women of all sizes. A full bust bra simply indicates that someone's bust measurement is approximately 4 to 5 inches larger than their band measurement.


To find the right fit for full bust lingerie, it's essential to consider both your band and bust measurements. It's common for bra sizes to fluctuate slightly based on the style of the bra or even across different brands. For example, one band size may work for you in one brand but not another, or a D cup in one brand might fit like a DD in another. This is why it's crucial to measure yourself properly and be aware of any variations between brands.

Final Thought

Bra shopping can often be confusing and frustrating due to the multitude of terms and sizing options. To ensure you find the perfect fit, it's crucial to know your accurate bra size. Even if you believe you already know your size, it's worth remeasuring every few years or before purchasing new lingerie. Your size can change over time due to various factors, so it's essential to stay updated.


Keep in mind that finding the right bra size may require some trial and error, especially across different brands and styles. If your straps dig into your shoulders or your band doesn't fit snugly, it's a sign that you might be wearing the wrong size. Use a reliable bra size calculator by inputting your bra band and bust measurements to confirm your correct size.


Remember, knowing your accurate bra size is crucial for your comfort, support, and overall confidence. By understanding the distinctions between standard sizing, plus size bras, and full bust lingerie, you'll be better equipped to find the right bra for you.
