Reviews

Almost Perfect

"I was happy to find a bra that is mostly organic with minimal bad materials. I'm a 32DDD and sadly that size is not offered. I really wish the sizes would be expanded. I chose a 34DD and it fits pretty well. The band is a bit too big on me though. Other than that, the material is soft and it's a good bra."

Thanks so much for making

"Thanks so much for making a making a comfortable non padded bra. I've been looking for years for something similar in the shops and took a leap of faith online and it has paid off !!! They are Now my absolute go too bra. Ive ordered a few more items in the past few days. Comfortable, easy to wash and dry, a great selection of colours and a fantastic fit ! Many thanks from a happy Irish customer"

I was looking for an

"I was looking for an organic cotton bra without polyester or nylon fabric. I liked the look of the full-coverage bra, but realized it has synthetic ingredients in the cups. This bra is extremely comfortable, lightweight, and gives more definition than many organic cotton bras on the market that give a uni-boob aesthetic, especially to those of us with a larger bust."

— Natalia S. (5/5)

Super Comfortable, Look Great, Perfect Under Clothes

"I love the fit, the fabric, and the look. I had a bra from years ago that worked for me, but then they stopped making it. And i have looked and looked, and bought and bought, only to have a drawer full of bras that dont fit well, dont look good under clothes, and/or are not comfortable. But I thought, i have to try again. And somehow i came across Organic Basics. And Wow! Am am i glad i did. The fabric is awesome and the style is perfect. They bras are comfortable, look good under clothes, and are just what i wanted and needed. I recommend Organic Basics to everyone. I'm looking forward to rooting around the website to check out other items -- if their bras are this great, i'm sure to find other fabulous items i need!"

Soft and comfortable real cotton.

"The core unlined Demi bra is comfortable and feels as close as one can get to being braless in an underwire bra. The cotton is very soft and breatheable. The underwire stays in place. If you’re a bigger person you may want to size up a bit to prevent spillover under the arm. It gives a very nice silhouette. It is a simple and attractive bra."

— Mechele E. (5/5)

Finally a Cotton Bra!

"I CANNOT believe I found a wired cotton bra!! I followed the size chart and I got a 38C. I think I needed a D instead, but I am nursing, so I am going to keep this size. It give the breast a nice shape and separation. I will be purchasing a black one as well. The band’s elastics don’t dig excessively like other bras I used, but they are on the slimmer side, so the bra shows if you are wearing a tighter shirt"

— Greta G. (5/5)

The bra is made of

"The bra is made of such soft material! Chose to buy by organic basics because they use organic cotton, which is so hard to find anywhere else. It's is a little small, so i would size up if your doubting what size to choose. :)"

— Hananja B. (4/5)

"I love this brand and I really love the light pink because I can wear it under lighter/sheerer shirts."

Love it but cup is slightly small

"Found the cup to be a bit smaller than other brands, but overall I really like the bra and will likely buy it in other colors"

— Lindsay S. (5/5)

It is the most comfortable

"It is the most comfortable bra with wires I have ever owned. The fabric is so soft and I am so happy it is 95% cotton. The fit is true to size."

— Sine F. (5/5)
