Finding Your Bra Sister Size: A Guide to Achieving a Better Plus Size Bra Fit

Are you tired of dealing with uncomfortable bras that don't fit your curves perfectly? Plus-size women often struggle to find the right bra size that offers both support and comfort. However, there's a lesser-known secret that can help you achieve the perfect fit – it's called "sister sizing." In this article, we will dive deep into the concept of sister sizing for bras, especially for fuller bust and big breasts, and how it can revolutionize your lingerie shopping experience.

Understanding Bra Sister Sizes

Clarification of Cup Size and Band Size

Before we explore sister sizing, let's clarify some basic terminology. In bras, the cup size is represented by letters (A, B, C, D, etc.), while the band size is represented by numbers (32, 34, 36, etc.). The cup size denotes the volume of your breasts, while the band size indicates the circumference of your ribcage.

How Sister Sizes Work

The concept of sister sizing involves finding bras that have the same cup volume but differ in band size. To go up a band size, you need to go down a cup size, and vice versa. For example, if you normally wear a 38E, your sister sizes would be 40D (one band size up) and 36F (one band size down). This means that if your perfect fit is unavailable in your preferred size, you can try a sister size for a similar fit.

Finding Your Bra Sister Sizes

To determine your bra sister sizes, follow these simple steps:

Identify Your Standard Plus Size Bra Size: Start by knowing your standard plus-size bra size, which is the size you commonly wear.

Going Up or Down in Band Size: To find your sister size with a larger band, add one to your current band size. For a smaller band, subtract one from your current band size.

Adjusting Cup Size: If you go up in band size, decrease the cup size by one letter to maintain the same cup volume. If you go down in band size, increase the cup size by one letter.

Examples of Sister Size Conversions: Let's say your standard bra size is 40G. If you go up in band size, your sister size would be 42F, and if you go down in band size, it would be 38H.

Benefits of Wearing a Sister Size Bra

Sister sizing offers several benefits, making it a useful tool in certain circumstances:

Availability in Various Styles: Sometimes, your preferred bra size might not be available in a specific style or brand. By knowing your sister sizes, you can explore more options without compromising on fit.

Addressing Fit Issues: Sister sizing allows you to address fit issues. For instance, if you find the band too tight but the cups fitting perfectly, try a sister size with a larger band for a more comfortable fit.

When to Use Sister Sizes

While sister sizing is a helpful tool, it's essential to recognize its limitations:

Exceptional Circumstances: While sister sizing can work wonders in most cases, there might be exceptions. Always try on bras to ensure the best fit, as individual body shapes can vary.

Avoid Stretched-out Bras: Don't rely on old, stretched-out big-size bras as a reference for sister sizing. It's best to start with a well-fitted plus-size bra as a baseline.

Final Thoughts

Embrace sister sizing as a fantastic way to explore different plus sizes for a better fit. Every woman's body is unique, and finding the right bra size can make a significant difference in comfort and confidence. If you're uncertain about your size, it's always a great idea to use Hermonisse's Bra Size guide for accurate sizing recommendations.
