Reviews

I love these briefs. Medium

"I love these briefs. Medium fit me perfectly, very soft, I am in love with organic basics to be honest, I have started taking my underwear more seriously alongside all my clothes in terms of quality and aesthetic and organic basics fits into that. Simple design, I especially like the colour choices."

— Ella F. (5/5)

returning customer from OB days

"Lovely Organic cotton briefs . Much improved fit overall , and so pleased that the thick elastic waistband has gone ! There is no creeping where you don't want them to go , no riding up . They are soft and are just such a great fit !"

— Yvonne H. (5/5)

new favorite cut of underwear

"Fit is true to size and material is comfortable. It's taken my ages to find underwear with decent coverage on the bum that doesn't ride up, and these are it! 5'2", 65kg, 98-101cm hips at the widest circumference. Size medium was a perfect fit."

— Chelsea F. (5/5)

Favourite knickers

"Great quality organic cotton! These briefs have a lovely feel and are very comfortable to wear. I thought they looked big at first, but that’s because there is more material and less elastic around the waist. They actually fit perfectly!"

— Isabelle B. (5/5)

J'aime le tissu et le

"J'aime le tissu et le toucher doux. Je pensais le rose moins intense (plus proche de la couleurs chair). Un peu trop rose bonbon à mon gout"

— Lucie S. (4/5)

Beautiful color and very comfortable

"I already owned these briefs in Marshmallow Pink with the matching bra, so I knew exactly which size to choose. I ordered my usual size XS, and the fit is perfect. The Soft Breeze color is absolutely beautiful and looks lovely with the matching bra. The material feels soft and comfortable, making them very pleasant to wear. A beautiful and comfortable set!"

— Victoria H. (5/5)

True to size, super comfy

"True to size, super comfy and love that organic cotton is used - it is so hard to find natural underwear these days! Got them in the sale, which made this pack great value."

— Eleanor H. (5/5)

Finally Wedgie Free

"Only underwear I’ve purchased that doesn’t result in constant wedgies every day. Big butt friendly. Would love to see more bright colors in the cotton material."

— Cheyenne W. (5/5)

I was very impressed with

"I was very impressed with the quality of the cotton and the softness of the undies, very comfortable and adjusted perfectly to my body. I loved the color olive green with a touch of fluorescent vibes, it looks great. I am new fan of organic basics!"

— Dalia Z. (5/5)
