Reviews

I can breathe!

"34C/36B sensitive to tight elastic bands inhibiting my breathing. Tried a Large since medium is usually too tight, and I have finally arrived at the correct size for my body. Nice soft stretchy cotton - I love it. Plus organic, also love that."

— Svea T. (5/5)

I don’t use it for

"I don’t use it for workouts, but everyday. And it’s very comfortable. If you are between sizes I would recommend sizing up. The fabric is super soft. Because of the cotton it is very breathable. Beautiful colour!"

— Sanne M. (5/5)

This is the first sports

"This is the first sports bra I have that is made of cotton and I love it! Nice shape and support, it feels very comfortable and is soft to the touch."

— Begoña A. (5/5)

nice, color, lovely fabric. slightly

"nice, color, lovely fabric. slightly too tight for me in the fitting of the underband"

— Hannah B. (4/5)

So comfortable but the cut

"So comfortable but the cut is a little low rise! The fabric is soft and thick, it seems like it will last"

— Beatrix r. (5/5)

Comfortable Support

"Extra comfortable bralette, purchased for wearing while breastfeeding (I just went one size up for more space). While comfortable, the bralette offers proper support."

— Alena G. (5/5)

finally found perfect size

"I am 34C/36B. I can’t deal with tight chest bands. Finally decided to try a Large and I am so relieved to have found support without restricted breathing."

— SVT (5/5)

Amazingly comfortable and supportive bra

"Love this bra so much that I now own it in 2 colors. It is super comfortable and provides excellent support! Probably my favorite of all the bras I’ve purchased from Organic Basics."

— Brittany (5/5)

Strange fit, nice quality

"Fit strangely, cut high in the armpit and on the chest but short in the strap. So for someone with a long torso and lower sitting boobs this was not a good fit. Fabric quality was great, color was as expected, and it did feel nicely supportive with the wide band. But for my body it had an uncomfortable and unflattering cut, so I returned it."

— Lara J. (5/5)

Perfect 👌

"Size M fits perfectly, I didn't have to size up like in other styles from organicbasics. I love this bralette, the fabric is soft and stretchy but doesn't wear out at all! It's my favourite choice to go out dancing because it gives good support while being very comfortable. I'll get another one for sure!"

— Laura Z. (5/5)

Q&A

I am interested in the flex racerback because it is made lf cotton. In the fabric description however i saw that the lining is made of synthetic fibers. Does that mean that indide of the bra that is actually in contact with skin has a layer of synthetic fabric ?
Hello Maria, Yes, the body is mostly organic cotton, but the inner lining (polyamide and elastane) is the part that sits against the skin for stretch and moisture-wicking comfort.
