Reviews

Good quality products! They feel

"Good quality products! They feel good on and even though I could have sized up they aren’t too tight amd still relly comfortable. I’m also in between sizes. The colors are nice and if washed according to directions the darker colors won’t stain lighter ones. I liked the shape! Would recommend!"

— Inka H. (5/5)

Dit is de eerst keer

"Dit is de eerst keer dat ik bestelde bij organic basics. Ik bestelde een setje slips, 2 basic topjes en een flare pants om te testen. Ik was super verrast door de kwaliteit en hoe goed alles overeen kwam met de foto’s. Alles zit super fijn en sluit goed aan. Ik bestel vanaf nu nog veel meer!"

— Stephanie B. (5/5)

cute color!

"I like these thongs a lot. The color is fun, and the fit is great. One note is that the actual size differs from pair to pair, which makes for extra returning for a different size."

— Lauren T. (4/5)

Favorite Underwear

"I wear these underwear literally every day. The rib fabric makes them extra fun and also extra comfortable, I love the fit, they are high waisted enough, which I would prefer a high waisted cut specifically, but I just go ahead and buy a size up and go high leg. I definitely recommend these and will continue to buy them again and again."

— Allison W. (5/5)

Really happy with my purchase

"These are a really great option for cotton underwear! The material is super soft (softer than other organic cotton underwear that I’ve tried) and feels very high quality. I would say they are true to size and I like the overall fit of them. I do wish they were a slightly higher rise but that’s just personal preference and wouldn’t put me off repurchasing."

— Macey (4/5)

Core Thongs

"I love the range of colors of the thongs and the quality seems great. One complication is that pairs of the same labeled size vary quite a bit in actual size."

— Lauren T. (5/5)

Be aware of sizing

"BE AWARE - that the size for the regular/core thong is not comparable to to the flex thong. I found it to be uncomfortable, but it might have worked better if I sized up. -the seams are also a bit sharp in my opinion."

— Ilena M. (3/5)

Almost perfect

"The fit and material of the core thong are pretty perfect. Soft and sleek and the cotton does feel high quality. Unfortunately after the first wash the elastic on one pair frayed and I’ve noticed wear on the seams of the gusset. I’m still happy with my purchase, but I’m not sure how long they will last! Maybe they need to be washed in an intimates bag or a more delicate wash…"

— Maia C. (5/5)

Love the shade of green.

"Love the shade of green. I found these ran quite small; but was able to size up after returning the first batch."

— Lauren T. (5/5)

"Very soft material to the touch. Organic cotton. The cut is really nice. My favorite out of all their things so far."
