Your Bra size is unavailable? 1 solution sister sizing

Updated: Oct 28, 2020




When you go for bra shopping, and you don't get your regular size available, what do you do? Don't buy the potential masterpiece bra you thought would be another charm of your lingerie collection? I hope this is not the scenario, the bra fitting assistance there must have suggested you an alternate size. And somehow it fits you, maybe slightly tight, or loose, in the band still the cups fit you right.

Did you think about how this can happen? How different size fits you?

The answer is, the circumference and the depth of the cup are the same, for the sister cup size and the underwire used is also the same, there is no difference in the circumference.



So, if your Regular Bra size is 34B your sister size is 32C, 36A

This is a kind of blessing as we might not get our sizes but still can purchase what we have marked.so the brand and you are nobody is in a loss.

I find this sister sizing cool and want to make everyone understand not to worry if you don't get your regular size.

To the sales representatives or Bra fitting assistance, this is crucial information to help the customers and the business.



When is sister sizing helpful?


When your bra band doesn't fit. If the bra is riding up, you can sister size down to keep your cup volume the same but add more support through the band. If the bra is so small you can't even fasten it but the cups are great, you can sister size up to feel more comfortable. In both cases, the cup volume will be the same.


When a bra is known to run small or large. Just like in clothing, bras do not have a standardized size system. Different brands use different measuring systems and size charts. Plus, there are often variations between styles for the same brand. If you're shopping online and know a certain bra runs small in the band, you can order a sister size up to get a better fit.


When you love a bra but it doesn't come in your preferred size. I like to wear 34C, but my sister size to a 36B when I use Jockey or Van Heusen. I won't get the same amount of support as I do in my preferred size, but I get to wear some really cute things that I otherwise would miss out on!

When you're buying a gift. And you're set on a certain bra for your recipient but it isn't made in their size, picking a sister size is a (slightly risky) way to give the gift you want to give—especially if the bra is a novelty style that isn't meant to be supportive.

I will give you some points to understand better, but nothing will make you compensate than trying these bra sizes yourself and find out which sizes works for you.

Find the size chart below, you might find sizes like size 28K and 48A on the same row, this extremes will not work, that is for sure but the depth of the cup remains the same.
