Nipple Coverage Without Padding: Inside the Concealing Petal Technology
THE END OF THE FOAM ERA. For 80 years, the bra industry has relied on bulky foam padding to hide nipples—a solution originally designed to add size, not intended for nipple coverage. We’ve replaced that outdated approach with our patented, low-profile, and padding-free concealing petal. Below, we break down the engineering behind this new concept and explain how it provides 100% concealment in our unpadded concealing bralettes, without changing your natural shape.
A Small Rant About Foam Padding
Let’s face it: foam padding is an antiquated shortcut for a problem the bra industry hasn’t solved. To understand why we’re still stuck with this bulky nonsense in our bras, you need to look at the history of padding itself. Frederick Mellinger, the founder of Frederick’s of Hollywood, introduced padding to the first bra in the late 1940s, specifically to add volume and create the “pin-up” silhouette popular at the time. Over the years, that same technology was simply rebranded for a dual purpose: to add size and to provide nipple concealment.
The truth is, the problem still exists. The bra industry didn't innovate for better concealment; it just repurposed an augmentation tool. We’ve all been there: wishing that "they" would finally develop a better way to provide coverage without the puffy, bulky padding that distorts your natural shape. For decades, women have put up with the trapped heat and the “orb" silhouette because, for the most part, the industry offered no alternatives.
NDA founder, Becky Connelly, approached the problem differently. While mass-market giants continue to rely on 80-year-old standards, she focused on engineering a solution specifically for low-profile concealment: the Concealing Petal.
After six years of perfecting the petal, she designed and launched the first nipple-concealing bra and Non Disclosure Apparel website in 2020. Becky says, "At NDA, we aren't just making a cool new bra; we are setting a nipple coverage standard that respects your natural silhouette. Women find us online because it's exactly what they're searching for."
Inside the Innovation: What is a Concealing Petal?
Women have long been stuck choosing between two options. One is unlined bras that are comfortable but don't hide nipples. The other is bulky, padded bras that say they hide nipples—though many still don't fully cover—and they change your shape and trap heat.
Having experienced this frustration firsthand, we recognized a huge gap in the industry. We didn't want a "slightly thinner" pad; we wanted an entirely new bra category. To achieve 100% concealment without using traditional padding insulation, we had to develop a new technology: The Concealing Petal.
Permanent Nipple Coverage: Built-In, Worry-Free Engineering
The petal is the highlight of our design. Unlike removable pads that shift, fold, and bunch, our petals are nearly invisible and permanently sealed between the inner and outer layers of our premium ribbed knit in the bra cup. It won’t move, become misshapen, or disappear in the wash, and it's so lightweight, you'll forget it's there.
The Technology Behind Seamless Nipple Concealment
Constantly improving for both strength and invisibility, our latest petal design features a construction that is thinner and more flexible than ever. We combine lightweight textiles with medical-grade, heat-melt film to create a micro-thin disc that is permanently centered and sealed into each cup during production.
-
The Superstar: The bottom layer of the petal—closest to the nipple and at the center of our patented design—is the strongest. It acts as a dedicated focal-point "shield" that neutralizes the nipple while remaining ultra-thin. This layer does all the heavy lifting to keep an erect nipple hidden from view.
- The Result: The tapered outer layers of the petal are made from lightweight fabrics and films that soften the edges of this strong, yet flexible, bottom layer. These "feathering" layers help the petal blend seamlessly into the bra, creating a smooth, natural silhouette that looks like you, not a volumized, busty version of yourself.
Perfect Coverage for Every Shape
Confidence shouldn't be limited by your cup size. We designed our collection to ensure that our nipple concealing bralettes feel just as secure on an A cup as they do on a G cup.
The Best Non-Padded Bra for Small Busts: No More 'Pad Gaps'
Smaller frames (A–C cups) often struggle with the "hollow gap" caused by stiff, one-size-fits-all foam. The Elli Bralette removes this bulk, providing a seamless silhouette that moves with you. Our integrated Concealing Petal stays perfectly flush, ensuring reliable, non-padded modesty that never looks puffy or fake.
Reliable Nipple Coverage for Full Busts (Without the Padding)
For fuller figures (B–G cups), finding comfortable coverage without feeling confined or adding unwanted volume can be challenging. The Gigi Bralette, our full-coverage style, offers gentle support combined with low-profile nipple coverage to help you feel secure and able to breathe. Our wide straps won’t slip off your shoulders either! You get 100% concealment without the bulk of non-breathable foam padding. It offers the natural silhouette of an unlined bra with significantly better nipple coverage than a padded one.
The Best Non-Padded Bra for Comfort and Modesty
You no longer have to choose between the airy feel of an unlined bra and the bulk of a padded one. We’ve created a "Third Category" of bra that offers the best of both worlds: the natural silhouette of a second skin and the total modesty of 100% nipple coverage.
Whether you’re looking for a smooth look under your thinnest tops or a comfortable everyday bra that actually performs, our built-in Concealing Petal delivers a seamless finish without the need for traditional foam padding. It’s a complete, all-in-one solution designed to move with you, not against you.
