Reviews

Beautiful selection of underwear and

"Beautiful selection of underwear and truly lovely fabrics ✨ You can really feel the attention to detail, comfort, and more natural/minimal materials. I also appreciate the simple yet elegant cuts - hard to find without synthetic fabrics everywhere. The whole brand feels thoughtful, timeless, and effortless to wear. It’s refreshing to see a brand focusing on both aesthetics and quality at the same time 🤍"

I like how soft the

"I like how soft the fabric is. My problem with thongs usually is that their is often not enough fabric in the middle part and with this undies it fits perfectly, wearing it is really nice because i know i won‘t slip and be uncomfortable when i am wearing it. The Design is rather simple but i like the rib texture and the grey colour. i would also say their a little bit tight on me but i think with the time they will be true to size."

— Sophie B. (5/5)

Super comfyy

"These are such a comfortable thong. They are a great, flattering shape and feel super lightweight. I'm always on the hunt for comfy thongs, that hug my body, and feel breathable. I'd heard about Organic Basics and so I brought a three pack so I could try them. Needless to say, I'm already thinking about my next order. . ."

I’ve Fallen In Love

"This was my first time trying Organic Basics, and I’m in love! They are sooooo comfy, and I love OB’s ethical and sustainability practices. I get excited to wear them every day, and can’t wait to purchase more!"

— Abigail B. (5/5)

DO NOT BUY!!

"Do not make the same mistake I did and purchase this underwear. They are so uncomfortable, thin, and cheaply made. The material is rough and digs into you. For reference I am 5'4 110 lbs, I purchased them in a size S and they were too tight. The thong portion of the underwear is so wide regardless of the size you purchase it would still be too uncomfortable to wear."

— Ana (1/5)

Great value and fabric!

"Loved! The size was a little smaller than I anticipated. Small fit well, but in other brands I’m a small and maybe would have gotten the medium if I had tried on first. Love the colors and the fabric. Would definitely buy again and great value. Highly recommend."

— Ise S. (5/5)

"Ribbed material is great. Perfect color. Slightly runs small."

Ribbed material is great. Great

"Ribbed material is great. Great color. Slightly runs small."

— Jacqueline L. (4/5)

"They run a pinch small but that might just be because it’s real material. If you are between sizes (ie S/M) go for the larger size! I’m a size S/M - normally a small for underwear, and I should have gone for a M instead of a S in this case. But very soft and high quality."

— Isabella (4/5)
