Our Purpose

MF Sea aims to align women with ideals of sustainable fashion.

We aim to create a garment made out of environmentally conscious materials, reducing our footprint on the planet. As a conscious creator, we celebrate the opportunity to include ideals of Mother Nature, of women, and a sustainable future together.

Sustainability is the fundamental value of MF Sea's mindset. We strongly believe that ‘sustainability should not be a marketing tool, it should be a requirement.

Viewing The World Through a Conscious Lens.

Being a conscious brand means to take back power, and support what we stand for, in an ever growing fast-fashion industry. Our goal is to make a difference by reducing our carbon footprint in a world affected by poorly managed value chains.

We define ourselves as a sustainable brand by embodying these aspects: by being a women-owned, locally produced in Portugal, using recycled and eco-friendly materials from the beginning to the end of our value chain.

We aim to give our consumers the choice to support a product that has the future of the environment in mind by creating versatile products that can be used many times, for many purposes across their lifespan.

We believe in using fabrics that matter.
