The best of both worlds—unpadded and underwired. This demi bra offers a flattering lift and natural-looking cleavage while staying comfy enough for everyday wear. Adjustable straps let you choose between straight or crossed, plus a hook-and-eye closure for a customizable fit. A go-to for those who want a little wired structure without extra padding.

  • Unpadded demi underwire bra made with 90% organic cotton
  • Offers moderate coverage and medium support
  • Demi-cup design, perfect for low-cut necklines, with wider-set cups for a natural, enhanced shape
  • Underwired cups for a light lift
  • Soft wear that lets your natural shape show
  • Adjustable straps that can be customized to be worn straight or crossed
  • Hook-and-eye back closure for a customizable fit
  • Made with 90% organic cotton
  • Added elastane for flexible comfort
  • Black: The one we restock most. Black goes well under everything and shows nothing.
  • For best hold, the underband and side wings should fit snugly
  • The wired cups should fully contain your bust—choose a size where you fill out the cups for optimal coverage and comfort
  • If your bust spills over the top or sides, try loosening the straps or sizing up
  • If the cups gap or wrinkle, consider sizing down

Reviews

Absolutely love this bra, fits

"Absolutely love this bra, fits well, gives perfect amount of support, no padding provides a nice more natural shape and look and the colour is cool, too - I did find that the underband was more stretchy then most bras, so had to downsize but I also really like the comfy stretchy material feel, so that’s fine"

— Jenna S. (5/5)

New daily staple

"I love this bra! The material is very soft and comfortable. It’s double lined so it gives me some coverage but it’s still breathable and flexible. The straps are comfortable— when completely extended and in the cross strap position they’re a bit snug. But it’s fine because the straps will likely loosen over time. Overall, I’d recommend this casual bra that provides everyday comfort and is high quality for a decent price."

— Summer P. (5/5)

Officially my go to bra!

"I struggle with bras, even when they’re the ‘correct’ size, they have weird gaps in the cups or the wire digs in. But that is not my experience with Organic Basics. I’m a 32A and a 32A in this bra fits perfect (I think this is because the cups may be a little small, as I am probably just barely smaller than an A cup). It is comfy and smooth under clothes! I am excited to find a bra I love that is also organic cotton."

— Alex H. (5/5)

Thank you

"I’ve been trying to find an organic cotton bra for the longest time and I finally found the one I’m never giving up. I don’t usually wear bras because of the comfortability, but I am truly amazed by this one and will be buying another one. I really love how comfortable it is and how much support it gives me."

— Kelsey K. (5/5)

Best daily bra ever?

"I have been using unlined bras for a while. This fabric is SOO soft, and doesn't feel like is going yo stretch to a point it doesn't give support anymore. It feel well made and comfortable. Exactly what I was looking for in a daily bra."

— Cala R. (5/5)

Great quality and fit

"My first impressions of these bras are amazing! They are super soft and comfortable and the fit is great. I bought my usual size and it fits perfectly."

— Macey (5/5)

very good material and quality,

"very good material and quality, love the cotton, if they had bigger sizes I would buy more, sad it goes only up to a c-cup on 70 band"

— Lisanna P. (5/5)

Comfortable and supportive

"I haven’t worn a bra with underwire for a long time but I found that these were comfortable and give a lot of support! I’m not sure if I ordered the wrong size but I have found that the cup itself is a little tight."

— Medbh H. (4/5)

LOVE!!

"I love this bra the color is perfect for under white tees. I love the shape it gives me. The overall design is so flattering as well. It fit true to size in all areas from the bust to the cups. The underwire is smooth and comfy too. A great everyday wear I reach for it so often."

— Kaya D. (5/5)

Great fit and overall feeling.

"Great fit and overall feeling. It’s been such a long time since i had a bra i genuinely enjoyed wearing, but these bras felt super comfortable and secure. The material is super soft and thick, which felt like it gave me the support i needed. I got them in black just as a first time try, but will definitely get more colors."

— Alessia G. (5/5)
