About Numi

Numi was born out of personal necessity. One day our founder, Michelle, realized she never wore her favorite clothes. They were either prone to noticeable sweat stains or expensive to dry clean. When she looked for a solution, there was nothing available. And so Numi was born.

Numi is a brand that celebrates what it means to be a woman. We make consciously created products that make life a little easier for us all and inspire a culture of kindness.

Committed to Sustainability

Being mindful of our impact has always been at the core of what we do. We like to think of it as a living commitment that grows and evolves with us. This year we're taking it further. We are in the process of auditing ourselves to see how and where we can be kinder to the planet.

Wonderful tops.

I have already owned these since the beginning of their being; they are lovely to wear and very practical too. Less laundry, extra warmth in the winter, and they can be quite stylish too.

Boatneck versatility

I like the boatneck option for shirts with lower neck lines. Comfortable and helps keep clothes fresher. The only thing is that I do wish there were options for a shorter sleeve.

The lace review

This was perfect, the material is soft and breathable. I wear this with my white shirts and it is completely invisible. I definitely recommend this product to anybody who doesn’t want to ruin their nice shirts.
