Reviews

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)

Better than expected

"The bra cup feels smooth on my skin, the material doesn’t irritate my breasts and the wire feels non existent. No cutting into my skin very form fitting silhouette"

— Kira H. (5/5)

I have been on a

"I have been on a long search for organic undergarments that are comfortable and have some amount of support without pads and toxic material. I took a chance on this Core Unlined Demi Bra, and now I wear it daily. I haven't worn underwear in years and I was hesitant, but this bra is really comfortable. Nothing digs or pinches, and the color disappears under clothing with no seams or awkward bra lines. It is very thin, very close to wearing nothing, so whatever your shape is this will not change that. Sturdy material and strong seams, very well made. 186lbs and I ordered 38D, fits perfectly."

— Tara P. (4/5)

Darn near perfect

"Took a bit to get used to wearing an underwire again but, I love these demi bras. No cup gap, the material feels wonderful. The only thing I feel could be improved is a wider band to help with back bulge. That would make this bra pretty much perfection!"

— Jeani S. (5/5)

These bras are THE MOST

"These bras are THE MOST COMFORTABLE thing in the world!! I’m usually picky about fabrics but these are so soft and light (makes sense as it’s mostly quality cotton) , which I’m definitely not used to as a D cup. I thought the lack of padding would be a problem but so far I’ve had no complaints! I rather prefer this shape as it adjusts to your body more easily."

— Matilde L. (5/5)

pls make 32D!

"I love this bra, new go-to. I wish organic basics would make a 32D! I got the 32C and the cups are a bit small, but still wearable."

— Nora V. (5/5)

Love it

"Comfy wiring, and the quality is great. Def a necessity in wardrobe."

— Sarah H. (5/5)

Comfortable, stylish and well-designed

"Comfortable, stylish and well-designed. Lately, I have struggled to find an affordable bra that fits comfortably and provides support, that doesn't give me underarm hangover and that looks good. This one does all three and at a reasonable price. Highly recommended."

— Lucy B. (5/5)

Very comfortable, lets your skin

"Very comfortable, lets your skin breathe and feels light, especially in the current heatwave in Europe."

— Katalin G. (5/5)
