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!

Amazing fabric, feels so good to wear and the colours are vibrant. A nice change to have options in clean undies. Will definitely buy more. True to size.

I absolutely love these underwear; they are the most comfortable and well made thongs I have come across. Hoping more colors are restocked soon!!

Amazing bodysuit! I'm glad I messaged the team to check what size would fit me. My bra size is 33A, Hips 38, Waist 28 in and the size M sits perfectly. Many compliments already received. Will purchase more of these in different colours.

I love the rust colour, it's very flattering to my skin tone, and the fit is so comfy that I have to keep checking that everything is where it's meant to be because I can't feel any uncomfortable pressure points. Will continue to get this one going forward.

Very well made, washes well and is comfortable. However the gusset is too short, wish it would come up higher!

It’s perfect for sauna and the fit is really nice too

Absolutely love this bralette, I was worried the knot at the back would be annoying under tight tops but it’s not.
I really like that I can adjust it as I want and need, it’s beautiful, soft and washed really well.
I’ve had 4 pairs now and loved them all.
