Reviews

i‘ve been looking for a

"i‘ve been looking for a bra like this forever. Its such a simple thing (compared to „real“ bras), but i never found one like this one; the band is wide (read: stable as in not cutting in the skin, but holding tight), the fabric is light and breathable, but enough to give form to the breast and there is no unnecessary seam, so you feel dressed, it looks good under t-shirts. the form is nice and i wouldn‘t mind if it might be seen, as it looks simply good."

— Janele S. (5/5)

Soft feel and nice design.

"Soft feel and nice design. I have been using this model since 2020, and the small improvements (e. g. smooth front instead of the fold) have only made the original product better."

— Begoña A. (5/5)

Would buy again.

"Love the colors. Only bought sale colors and am so very happy with each of the bras I've boughten from OB. Organic cotton, high quality, at a very fair price."

— Julia C. (5/5)

"Sooooo comfortable, and a perfect model for breastfeeding as well! + it looks good"

The perfect bra

"These are the only bras I wear. They are super comfortable and they breathe."

— Laura R. (5/5)

everyday go to

"This is my everyday go to. Took a moment to figure out the sizing and I had to size up a little for the band not to be too tight and restrictive. It is also a bit of a high/wide cut around the armpits for me (which doesn't always work with camisoles) but it is such a comfortable bra! I have it in two colors."

— Nikita P. (5/5)

Soft, flexible and well made

"Soft, flexible and well made bras, I reach for them time and time again! Love the brand and won’t buy anything else after other underarms after trying these !"

— Sammi M. (5/5)

A Lovely Colour

"I own another Core Triangle Bralette in a different colour, and this one is slightly smaller in the cups in comparison to the other one in the same size. It's flattering and comfortable. It also provides enough support for everyday wear. I'm size 32DD, and I ordered size M, which first perfectly well. The fabric feels buttery."

— Albina H. (5/5)

Ok bra

"I like that this bra is organic cotton and soft. It does have some issues though. I feel like it doesn’t hold my cleavage that great because when I bend over, everything spills out. Also, my nipples show through in most shirts. The other thing I don’t like is that the seam is pretty visible."

— Taylor T. (3/5)

Not impressed

"Really odd fit and shape, the bra gapes a lot at the top and the under band is weirdly thick. The fabric is not as soft as I was expecting. Annoyingly its so expensive to return that it isnt worth it so I will have to re-sell or give away. I think the brand need to make it more obvious that they are based in central Europe, I would not have bought if id known this prior."

— Ms m. (5/5)
