The Hi Thong in Organic Cotton Rib – Rust brings together comfort, movement, and quiet strength. Made from GOTS-certified organic cotton rib, it feels naturally soft and breathable against the skin, with a hint of elastane for gentle stretch and a fit that moves effortlessly with you.

This Hi Thong in Organic Cotton Rib features a sporty high-line cut that elongates the body and offers light, barely-there coverage. A thin gel leg liner helps to minimise visible panty lines, creating a smooth, seamless finish beneath your clothing. The rich Rust tone adds warmth and depth earthy, confident, and timeless.

Every Hi Thong in Organic Cotton Rib – Rust is consciously crafted from non-toxic fabric, plastic-free, and made to last. Designed for everyday wear, it’s underwear that feels as natural as it looks soft, sustainable, and made for real life.

At Stone.kin, we believe true comfort is intentional simple materials, clean lines, and designs that move with you.

So in love with this top- I am actually going to wear it as a bikini on the beach. The softest highest quality material and the cutest design!

as always, the quality and comfort of the fabric is amazing, these are my favourite undies. The new colours are lovely but I couldn't buy the more popular ones because of sold out. I had the first first colours so I wanted to obviously keep buying this brand next ones.
I do think the previous elastic band colour which was grey with the brand name in black was more appealing and had a more serious cool and interesting look, it contrasted much better with different colours. For me at least it was more calling.... hihihi

Anyways, keep on producing them. they last long and the fabric is super comfy and doesn't flatten your butt, it makes it look nice!

I bought one of these to try and liked it so much I ordered two more. They’re super cute, comfortable, and feel great on. So soft! Love this racerback style. I’m a 34A/10A but usually size up because I don’t like a tight bra. The size L is perfect - not too tight/no riding up. I feel like I finally found the perfect bra after literally decades of looking.

They're amazing. I bought three. It was so nice to open up the packaging (compostable) and the fabric smelt like it came from the earth - not a plastics factory. They smelt so good I didn't even feel the need to wash them first like you do with other new clothes. They're made well and are very comfortable. I will be back for more.
