The Truth About Bra Sizing: Why It Matters More Than You Think

Let’s talk about something that’s wildly misunderstood but completely life-changing when you get it right—bra sizing.   

Did you know that around 80% of women are wearing the wrong size bra? And honestly, it’s not surprising. Most of us were never taught how bras should actually fit, and with sizing inconsistencies across brands, it’s no wonder women give up and just settle for ‘good enough.’ But the truth is, a properly fitted bra can change everything —how you feel, how your clothes fit, and even your posture!  

Getting your bra size right isn’t just about numbers and letters—it’s about how a bra works for your body. Here’s why a great fit is non-negotiable:  

- Comfort is everything: A bra should never feel like something you need to rip off the second you get home. The right fit means no digging, no slipping, and no “I can’t breathe” moments.  

- Better posture & support: If your back and shoulders ache, your bra might not be pulling its weight (literally). A well-fitted bra supports your bust without straining your body.  

- Clothes sit better: Ever tried on a dress and felt like something was off? The right bra lifts and smooths, making your outfits look and feel amazing.  

- Prevents discomfort & long-term damage: Ill-fitting bras can cause everything from red marks and chafing to stretched breast tissue over time. No thanks!  

- Confidence boost: There’s something about perfectly fitting lingerie that makes you stand a little taller and feel really good in your skin.  

Now, whether you’re a lover of classic bras or you swear by backless solutions like stick-on bras, shape tape, and ultra-thin nipple covers, knowing your true bra size will make all your lingerie work so much better for you.  

And if you’re sitting there thinking, “Well, that’s great, but I have no clue how to figure out my size,” don’t worry - I've got you. In the next blog post, I’ll walk you through how to actually find your perfect bra size (and no, it’s not just a measuring tape and a hope for the best).
