Have you ever walked into a lingerie store and found that more than one bra size fit? If you said yes, you’re not alone. Bra fitting is much more complex than we’re led to believe. Since most of us buy the same bra size over and over again, we may never stop to think about why bra sizing is not determined by body measurements alone.

There are actually a number of factors that go into determining a bra size and a bra’s fit (especially if the best fit isn’t in your usual bra size). As such, bra fitting is more of an art than a science and your bra size is more of a guide than a set number. Sure, there is science (and math) involved throughout the bra’s development and production stages and in the fitting room when you’re getting measured, but there is no perfect way to measure for a bra.

Ready to dive deeper into this complex topic and learn more about bra fitting along the way? Let’s go!

Your bra size is based on a number of factors

First things first, a bra size is so much more than a number and a letter. Your bra size is the sum of your breast shape, breast height, fit preferences, and chest, overbust, and underbust measurements. Since bra fitting isn’t an exact science, bra fitters consider all of these factors before giving you bras to try on. They know which bra styles work best for full busts, which work best for small busts, and which work best for asymmetrical and wide set busts – just to name a few. They also know exactly which bras have narrow wires (good for full busts and small busts) and which bras have shaping and support for asymmetrical breasts and wide set breasts among many others. Basically, bra fitters are part bra fit aficionado, part therapist, and part lingerie encyclopedia.

Bra fitting helps you find a comfortable and supportive bra

Sometimes the most supportive bra is in a bra size you wouldn’t normally wear. We all know how sizing can vary between lingerie brands, making it difficult to find a consistent size that fits you across all brands. Because of this, you might find that you wear your bra sister size in one line and your usual bra size in another. Also, depending on the style and the bra’s fabrication, you might find that you need to go up or down a band size or cup size entirely to get the best fit (thus diverging from your bra sister size to a whole new bra size). Bra sizing can quickly become confusing – which is why we need bra fitters.

Bra fitters aim to bridge the gap between the sizing of different lingerie brands and your unique measurements and fit preferences. Most bra fitters have tried on all of the styles they sell and can spot an ill-fitting bra a mile away. Most importantly, professional bra fitters are there to help you find a bra that fits comfortably and feels supportive – so you don’t have to try on hundreds of bras on your own to find it.

Though your bras might be cut and sewn within a pre-approved set of measurements, bra fitting is truly an art and not a science. We hope you learned something new about bra fitting from this article. As always, we’d love to hear your thoughts in the comments below!
