The Foolproof Way to Find Your Real Bra Size, According to Bra Enthusiasts
Let’s face it, nine out of ten of us are probably wearing the wrong size bra right this moment. Incorrect fittings from Victoria’s Secret years ago have left many of us believing we’re a 38B instead of a 32F, or a 36DD instead of a 34G. If you’ve long thought of yourself as having a certain size bust, we know that sounds like a huge discrepancy, but an important part of transitioning to a correctly fitted bra is being able to overcome the sticker shock of a higher or lower cup size.
One community on Reddit called A Bra That Fits believes it has designed a system to finally find your actual bra size, all from the comfort of your own home. What’s more, they’ve crowdsourced recommendations for every size, including some of the toughest sizes to shop for—the DD and up range.
Below, find r/ABraThatFits’ guidelines for measuring yourself at home, plus the best-fitting, most comfortable bras for big boobs.
How to find your bra size
With a soft measuring tape, measure your underbust three times directly at the point where your breast tissue attaches to your torso—first measure loosely without allowing the tape to indent your flesh, then measure with the tape “comfortably snug” so that it indents the flesh slightly, and lastly measure as tightly as possible while exhaling completely.
Now, measure your bust three times as well. Start by measuring your bust (without wearing a bra or shirt) while standing. Then, measure while bending over at a 90º angle, and finally, measure while lying down on your back.
Now, enter the above six measurements into this bra size calculator.
How to find your bra shape
As much as we wish that’s all it took to find a perfectly fitted bra, we all know bodies are unique and bras are complicated, so there is one more step. To find your breast shape (and in turn, the proper bra you should be wearing) you’ll need to figure out your projection and your fullness.
To determine whether your breast shape is more projected or more shallow, try holding up a pencil with the underside of your boob. Projected breasts have more of a fold on their bottom half and should be able to keep the pencil in place, whereas shallow breasts have less of a fold or no fold at all.
Shallow breasts should pay close attention to that characteristic when selecting bras. Projected breasts should refer to their fullness level specifically. To determine your fullness, without wearing a bra, bend over 90º from the hips and assess your profile in a mirror. If you have more tissue above your nipple, your breasts are full on top, if you have more flesh below the nipple, your breasts are full on the bottom. If the flesh seems evenly distributed above and below the nipple, your breasts have even fullness.
With your true size and fullness in mind, keep scrolling to see the r/ABraThatFits’ best recommended bras for you, narrowed down to the five highest rated on Amazon. See why Reddit (and we) love these picks.
