Reviews

This is a well constructed

"This is a well constructed item and I'm loving the colour! There is more elastane then I thought there would be - more than ideally I would like - ( I should have read the description closer, I'm guessing) and the size Small I bought just about contains my 32 C/D bust. I will certainly be buying more items from Organic Basics."

— Elizabeth S. (5/5)

Great everyday bra but size up!

"Lovely soft fabric! I originally bought xs based on the measurements but returned for a s. Definitely size up, especially if you are a larger cup size - I’m a D/DD. I’ve since ordered the s+ which I prefer for everyday wear due to the thicker straps and more coverage in the front. I’ll be keeping the s for lower cut / thin strap clothing."

— Rachel S. (4/5)

Gorgeous colour, perfect fit

"Perfect summary colour and the softest material. Purchased a size s, as a size 8(uk), 32c. Fastens on the tightest hook and eye so could probably have gotten away with an xs too"

— Louise R. (5/5)

Perfect quality and fit

"Gorgeous bralette. Very soft and smooth material, the colour is so pretty and unusual. True to size, I got a small as a 5”, size 8(uk), 32C, fastened on the tightest hook and eye."

— Louise R. (5/5)

Beautiful colour, really bright red.

"Beautiful colour, really bright red. Had a bit of a problem finding the right size. I normally wear an L+ bun unfortunately it’s not available in this colour. According to the size chart I would need an L but that was really unsupportive compared to L+. Thinner straps,side piece etc. Changed for an XL which was better for these parts but the coverage in front was not enough for me, when moving my boobs would fall out. But because I love the quality and colour so much I made an adjustment myself, sewed the lower parts of the cups together, now it’s perfect!"

— Loes F. (5/5)

Core Triangle Bralette

"It's a nice one, but for large bust had to exchange for 2 sizes up. The one thing I wanted to mention, a lot of bra have natural cotton material, but the lining was 100% or 50 % synthetics. That is so frustrating, I wanted to buy couple more bras, but didn't because all the linings are Polyester, nylon or Spandex"

— Tetiana L. (5/5)

My favorite bra! So comfortable,

"My favorite bra! So comfortable, I could sleep in it. Excellent thick cotton fabric that gives just the right amount of support for simple daily wear, while still being breathable. I bought two last year and reach for them all the time. More recently, I got four more of the same bra, which I never do, but these are just too excellent a product. Very small for packing too, in case you travel with them. They seem to age well too, and they are very flattering (my husband confirms)"

— Ashley A. (5/5)

Soft & Comfortable

"I ordered one in blue and one in pink, and they didn’t disappoint! I feel like I am not wearing a bra, because they are so comfortable. Not my last buy from Organic Basics."

— Frederikke S. (5/5)

Lovely shape but a bit

"Lovely shape but a bit loose in the under-band. The fabric is thick and gives good support."

— Biljana M. (4/5)

Would buy in every colour

"Beautiful colour, would class as a neutral shade. Bought size s as a 5”, size 8(uk), 32c and it fits beautifully."

— Louise R. (5/5)
