Clash Tee

Lifestyle Brand


Clash Tee is a collective of creative girls and great friends committed to expressing ourselves freely and connecting deeply. We believe that beauty and style come naturally when we celebrate our authentic selves and choose fashion pieces that speak to our individual spirits.

We live a lighter life full of wide smiles, loud music, sandy feet, windy hair, and sun-kissed skin. We care less about selfies and more about tight hugs. The sound of our friends’ laughter is our favorite.
A Clash Tee girl is open-minded, sincere, and full of life. She’s you.


Created at the end of 2018, Clash Tee emerged to share a passion for casual, comfortable, affordable, and authentic fashion.

Our designs are inspired by the colorful fashion of the world’s cultures, creativity, youth, and the abundance of Brazilian life, our founder’s home country.

Our products are designed in Brazil and produced in small batches. Each piece is exclusive and limited edition.


Clau Mattos is the heart, soul, and principal designer behind Clash Tee. She’s been sharing her spirit through personalized looks and standing out for her creativity ever since she was a kid.

Before launching Clash Tee, Clau worked as a personal shopper and fashion consultant for major Brazilian brands like Cantão, BOBSTORE, Arezzo, Bobo, Lelis, and MAC Cosmetics. Today, she mixes styles, textures, and materials to create unique combinations that communicate freedom, self-expression, and a refusal to conform to the status quo.
