About Us



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 | Founder of Clash Tee

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.


Rio de Janeiro | Brazil

With deep roots in Brazil, we begin our design process there. We’re inspired by the authenticity and flair of Brazilian fashion and aim to infuse these very same qualities into each of our pieces. 

The bright colors of carnival, the sounds of the samba drum, the scent of the sea, fresh flowers, and sunsets that turn the whole sky purple are our muses.


A Message From Clau

“You will never be happy wearing something because you think it will make someone accept you or like you more simply because it’s on-trend. Being yourself is a revolutionary act. It takes courage, but it also brings a lot of happiness. If you want something more liberating than choosing a piece of clothing, think about why it represents you. Why are you drawn to it? What can it tell you about yourself that you don’t already know?

I often look around and see girls uncomfortable with the look they chose just because they wanted to be like their friend. It reminds me of when I started wearing heels because my friends did: what torture! I finally learned to be honest with myself and say: no, I hate heels! Why would I wear something that doesn't represent me? We have to stop sabotaging ourselves daily. Instead, let us choose acceptance, love, and happiness!"
