Reviews

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 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)

Fav Bras

"From the cut to the sizing to the cotton fabric, these are hands down my fav bras ever. I threw all my other bras out! Buy it buy it buy it and you won’t regret it. Organic Basics also has great point redemptions unlike other major brands."

— Greta P. (5/5)

Fav Bra

"These bras are so comfortable. The soft cotton material is thin but very supportive. I don’t even feel like I’m wearing a bra when I have it on. I’ve never had to exchange a bra from Organic Basics, and never will! They’re the best."

— Greta P. (5/5)

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."

— Chelsey N. (5/5)

Love them!

"Super soft feel, good support but not overly excessive. Comfy underwire. Looks great in a t-shirt even with a larger cup size."

— Emily T. (5/5)

The fabric is very soft

"The fabric is very soft and comfortable, everything I’d expect from organic cotton. The silhouette and shape is perfect and is exactly what I was looking for. Still has a shape that is more rounded than a bralette but as comfortable and flexible as one"

— Hiilei B. (5/5)

Size Chart is wrong but the bras are right!

"LOVE these bras BUT their size chart is way off. My underband measurement is 31inches and overbust is 37 inches so if I followed their chart, I would have been a 36B. . . I previously worked for a bra retailer so I suspected the band would be too big and got a 34C. The band was perfect but the cup was wayyy too small so I exchanged for a 34DD and that fits perfectly! The band sits evenly all around my torso, the center gore sits flat, and no spill over. The material is great, thick enough that it keeps the nipple from being visible in t-shirts, but still breathable. The cups are supportive and just gently round out my natural shape instead of having to fill out a molded cup. LOVE that they're mostly cotton. They look attractive while still being comfortable. The dusty rose color is a nice change up from my usual beige without being super loud. I'm going to order more!"

— Jordan G. (5/5)

Amazing

"So comfortable ! Love the support the wires give. Really flattering cut and perfect fit. Finally found my everyday bra. Will be buying more. Really happy with it, have already bought another and about to order one more."

— Kate D. (5/5)
