Our story

Hi there! We're Raquel and Sofia, twin sisters, best friends, and the designers behind SIZ.

Our story began with a shared passion for fashion and a desire to create something of our own. After studying Fashion Design and spending time designing for others, we decided to follow our own path and build a brand that reflects not only our aesthetic, but also the way we see the world.

Founded in Sesimbra, a little town between the sea and the mountains in Portugal, SIZ grew from a simple idea: fashion should make us feel good, without making us feel guilty about the way it's made.

We believe in creating fewer, better pieces. Clothes that feel special when you wear them, that become part of your everyday life, and that stay with you long after a season or a trend has passed. That's why we work with natural and more conscious materials, including organic and deadstock fabrics, and produce locally in Portugal, in small batches and with care.

From the first sketches and fabric research to patternmaking, fittings and the final details, we're personally involved in every step of the creative process. We love experimenting with shapes, textures and colours, finding that balance between clean lines and a little bit of attitude. And whenever we need an extra pair of hands, we choose to work with local professionals who share our appreciation for craftsmanship.

Over the years, SIZ has grown beyond our little atelier, reaching women through our online store, pop-up experiences and independent multibrand stores in Portugal and abroad. But even as we grow, our purpose remains the same: to challenge the way we think about fashion and show that style and conscious choices can go hand in hand.

For us, SIZ has always been about more than making clothes. It's about creating with purpose, wearing with intention, and finding beauty in the things that truly matter.

We're so happy you're here. Welcome to our world!
