About us

We create activewear to perfectly move with your body. SEFI began with the belief that comfort and confidence shouldn't be compromised. Every piece has been designed to help you feel confident, comfortable and feel your best, whatever the activity. The styles are authentic, versatile, and can be styled together effortlessly.

SEFI was founded to fill a void in the activewear market. Our founder, Stef Williams, has worn activewear her whole life yet struggled to find designs that were both functional and flattering. She wanted timeless, stylish, high quality activewear that moved with her body - ready for workouts, weekends, and everything in between.

Driven by this vision, Stef rigorously tested fabrics and fits, aiming to develop a collection that complements the natural curvature of a woman's body and therefore maximising the fit, comfort and versatility. The result is our SEFI pieces, crafted from premium fabrics with lightweight sweat-wicking technology for the ultimate second-skin feel.

This is just the beginning of our journey. SEFI grows based on feedback from women like you who inspire our designs. Join our community – we create for you.
