How It Started

As two women in our 30's, we couldn’t find underwear that actually worked for real life. We wanted cotton that was truly 100% organic, no added synthetics hiding in the fine print; and a high performance pair that could keep up during sweaty workouts and our most active days. We had upgraded everything else in our closets, but somehow, not the first thing we put on every day.

The underwear we found was either poorly made, pretending to be “eco,” or uncomfortable. Nothing felt well-made and functional.

So we created Netherlin, a line of underwear staples to ground your wardrobe and keep you ready for whatever the day brings. We bring together the best materials for your body with design that fits how you actually live.

These are foundational pieces. Made with the same care as everything else you reach for on repeat.

We’re Ally & Kelsey,
the duo behind Netherlin.

A little about us and the styles we're each wearing.

"I like things that feel good on my skin & don’t ask for attention. Cotton is an easy yes."

Most days I wear the Cotton Collection. It’s breathable, organic, and soft in a way that just makes sense. These days I care less about underwear lines or shapewear and more about how things feel and what they’re made from. It’s comforting to have 100% organic cotton as the layer closest to my skin.

From yin yoga to the farmer’s market, the Hipster is my daily go-to for comfort.

"I need my clothes to keep up - simple, stylish, & comfortable enough to wear all day."

The Movement Collection is what I wear most. It is light, seamless, and dependable. When winding down at night, I reach for our Cotton French-Cut Brief. It’s soft, relaxed, and still makes me feel pulled together with its flattering high leg.

The Movement Thong is my everyday staple because I can set it & forget it.
