Dubh Celtic Embroidered Shirt

The Dubh Celtic Embroidered Shirt is a modern take on the traditional grandfather shirt, combining clean lines, substantial natural fabric and subtle Celtic-inspired detail.

Made from 200gsm heavy cotton slub, this men’s black collarless shirt has a soft textured finish and enough weight to make it comfortable for year-round wear. The grandfather collar and buttoned placket keep the shape simple and timeless, while the longer cut gives it an easy, relaxed silhouette.

A delicate Celtic knotwork embroidery at the cuff adds a refined point of detail, inspired by fine-line tattoo art and traditional interwoven Celtic forms. The sleeves can be worn full length or rolled and secured with the button tab for a more casual three-quarter style.

Easy to pair with trousers or denim, this men’s black cotton shirt works equally well for everyday wear, festivals, heritage-inspired styling and relaxed occasions where you want something distinctive without feeling overly formal.

🧵This has been designed by the designer and founder of Celtic Fusion; Regina Tierney. Her inspiration comes from her home place in County Clare in the West of Ireland where the Celtic Fusion Studio is based. Celtic Fusion was designed to create a connection to nature through unique clothing. The designs are inspired by Celtic spirituality and ancient paganism - beliefs centered around the natural world and the cycle of life. So, naturally, sustainability and ethics are a top priority in the construction of the clothing you purchase. We hope to create a new standard for the impact of fashion with our choice of fabrics, construction processes, and positive work practices. Our production would not be possible without our skilled team in India where Irish designer Regina Tierney works for 3 months of each year over-seeing our entire work process and production in every element to create our ethical designs.
