Hi, I’m Kate – fashion has always been my passion. For over 30 years, I’ve loved helping women find pieces that feel timeless, a little different, and truly special. Diffusion started as a boutique in Clontarf, Dublin and has transitioned to a thriving online only store over the past 10 years. Whether you’ve been with us from the beginning or you’re just discovering us now, I’m so glad you’re here.
