Crafted with Heart. Worn with Pride.

With over 29 years of dedication, this Kildare-based brand has become a quiet cornerstone in Ireland’s evolving clothing and lifestyle scene.

Now, as we (Conor and Maeve) prepare for a well-earned retirement, the doors of our beloved store will soon close for good. To mark this special moment, we’re holding one final Clearance Sale.

A heartfelt thank you to everyone who has supported us over the years.
