Wearing the wrong bra size is a common problem among women, and it can cause discomfort, pain, and even posture issues. But finding the perfect bra is not always easy and can be overwhelming, especially if you don't know your exact size. Fortunately, there is a solution: the sister sizing method, which involves equivalent bra sizes.
There are times when the bra size you regularly opt for doesn’t fit you. Ever wondered why you face this situation despite buying the bra size you’ve bought a million times before? Well, remember that several factors, such as the bra fabric, manufacturing variations, presence of underwires, cup shapes, and padding levels, might contribute to the way a bra fits you. This is where the concept of sister size comes into play.
What Is Sister Sizing?
Sister sizes can be a savior when the bra in your actual size doesn’t fit properly. In simple terms, sister sizes are equivalent bra sizes. The cup volume of your actual bra size and sister size bra remains the same. That’s why fitting experts recommend trying sister sizes when your original bra size doesn’t fit or is unavailable.
I Want to Know My Sister Size
Every bra size has four sister sizes, but when selecting sister-size bras, you can ideally consider the nearest two for the best fit.
Sister Size Up
For instance, if your bra size is 34C, your sister size up will be 36B (one band size higher and one cup size smaller).
Sister Size Down
Similarly, if your cup size is 34C, your sister down will be 32D (one band size lower and one cup size bigger).
Opt for a sister size up when the band of your actual size bra is tight or too small. On the other hand, go for a sister size down when your cup is too small.
Should I Definitely Opt for Sister Size Bras?
Please remember that there are many reasons why a sizing bra doesn’t fit you. Note which attributes of your bra need to be corrected in order to achieve the right fit. This will help you get a bra that fits the way it should.
It is also important to understand the physical changes in your body that may lead to a misfit. Puberty and pregnancy are stages when your normal bra would do no justice. So, trying sister sizes would be the ideal option here.
Moreover, an ill-fitting bra can cause a lot of discomfort, neck and shoulder pain, and posture problems. So, it is better that you go for sister sizes rather than stick with the same uncomfortable bra.
If you are still not satisfied with the sister sizing concept, we recommend you measure yourself again for the correct bra size before proceeding with the shopping.
