About Us

Hello and welcome!

I’m Kate, founder of Diffusion.

From our roots as a renowned fashion-forward boutique in Clontarf, Dublin to our growing online presence, we are proud to be serving our customers for over 30 years.

Since 2015, we have been fully online and I’ve had the joy of curating beautiful pieces that make women feel effortlessly stylish. Diffusion is more than a store – it’s a space where timeless fashion meets everyday ease, with every piece handpicked to mix, match, and be loved for seasons to come.

Thank you for being here – I hope you find something that feels just right for you.

Warmly,

DIFFUSION Boutique - Established 1991.
