We’ve created half-cup bra sizes so you can find a design that fits you perfectly. Our 30D bra collection is designed with your comfort and style in mind.
Here at ThirdLove, we believe that every woman deserves to wear a bra that fits her like a glove. This means no gaping, overspilling, or digging into your skin. You can finally put those bad bras behind you and choose the ones that feel smooth and soft against your skin. We also know that size is everything for a bra that can support you throughout the day. That’s why we’ve created half cup bra sizes, so you could find a design that fits you perfectly. We’ve designed our 30D bra collection keeping both your comfort and style in mind. Our bras are lightweight and will mold to your breast shape for ultimate lift and support.
If you’re looking for a wireless bra that feels silky smooth then opt for ThirdLove’s Form 360 Fit™ Wireless Bra. It features comfy seamless stretch fabric and built-in foam cups that lift your ladies and help create a streamlined silhouette. For those of you who think you can’t wear a bralette if you have a 30D bra size - we have good news! Our Everyday Lace Full Coverage Bralette is a perfect combination of glamorous style and gentle support. It’s made with scratch-free lace and will feel lightweight and airy when you wear it. Boost your confidence with ThirdLove’s semi-sheer Bare Mesh Wireless Bra. This design will lift and shape your breasts while giving you enough support to feel great no matter what you wear. If you’re into sports, we have something for you, too. ThirdLove’s Flex Seamless Racerback Sports Bra combines cuteness and functionality like no other design has ever done before. Enjoy the sleek-looking engineered knit zones that will support your breasts and prevent them from bouncing while you’re getting active.
Forget about boring bras that all look the same. At ThirdLove, we’ve created a variety of fun colors to fill up your top drawer to the brim. You can still find classy black, taupe, and white designs if you want to look chic. But if you’re looking for something extra, choose from a rich palette of cloudy blues, mint greens, blush pinks, and stormy lilacs. You can now wear lingerie that matches your mood and makes your day a little brighter. All our designs are made of premium fabrics like organic cloud cotton, soft lace, cool-touch microfiber, stretchy polyester, and many others. This means you can always find a suitable design if you have sensitive skin.
Bra size 30D should hug your breasts like a second skin. Always aim for a snug fit that doesn’t feel overly tight. You should be able to raise your hands without the bra riding up. If it does, you need to try wearing a different size. Your breasts shouldn’t spill over the cups of the bra. Make sure they fill the cups nicely. The underwire should sit flat on top of your rib cage, comfortably supporting your breasts. If there’s poking, that’s a definite no. Make sure you adjust the straps to prevent them from slipping. They should sit in the middle of your shoulders without digging into your skin.
When choosing a 30 D bra, always pick a design that feels snug and comfortable. It should smooth your curves while providing enough support no matter how much you move. Our wireless designs are perfect for everyday wear. If you want something to relax in and spend a whole day chilling, you can opt for a soft lacy bralette that will hold your breasts in style. If you’re still not sure what bra will fit you best, we’ve prepared a Fitting Room Quiz for you. Answer a few questions to finally choose a bra that both looks and feels good.
