ABOUT

Hi, I’m Jeroa Tomasowa.
A Creative based in Amsterdam and Barcelona.
Design has always been my language of self-expression.
A way to stand out, challenge norms and shape identity.

My work moving forward focuses on authenticity, fearless creativity, and celebrating individuality through design.

From fashion label and product development to hospitality concepts, branding and social storytelling. Every project is approached with aesthetic precision and a clear vision.
