Description
Crafted in Dublin | Woven with Story, Tailored with Soul
Thoughtfully made and rooted in Irish tradition, the Behan Grey Herringbone Waistcoat blends timeless design with the quiet strength of heritage craftsmanship. Woven in a classic grey herringbone tweed, this piece carries the subtle texture and strength that have defined Irish tailoring for generations—refined, versatile, and full of quiet character.
Every waistcoat is shaped by hand in Dublin, where skilled tailors bring years of experience to each stage of its making. From the carefully balanced cut to the smallest stitch, it's a piece that honours both the wearer and the maker. Whether styled for day or evening, it’s made to fit effortlessly into your life—layered over a shirt or beneath a tailored jacket, adapting to the rhythm of your day.
Inside, a world map satin lining offers a gentle nod to the global Irish spirit—a tribute to journeys taken, stories shared, and the lasting connection to home. At the back, an adjustable belt lets you personalise the fit, while the full cloth back ensures comfort and polish in every setting.
Inspired by Brendan Behan—playwright, poet, and one of Ireland’s most colourful literary voices—this waistcoat channels a sense of bold individuality and thoughtful rebellion. Like Behan himself, it celebrates the layers that make up identity: artistry, resilience, and a touch of wit.
Why Irish-Made Still Matters
Handmade in Balbriggan, just outside Dublin, this waistcoat is cut and sewn in small batches by expert tailors. The grey herringbone tweed is selected for its rich texture and enduring structure—designed to hold its shape while softening over time. By keeping production local, we not only preserve time-honoured skills but also ensure that every detail is intentionally crafted. It’s fashion made slow, made well, and made to last.
Grey Herringbone Tweed
Herringbone tweed is easily recognised by its subtle V-shaped pattern, which gives the fabric natural strength and structure. Traditionally woven from wool, it is breathable and insulating—ideal for cooler days and year-round layering. The grey variation offers unmatched versatility, pairing effortlessly with both casual and formal looks. With every wear, it becomes more personal—softening slightly, but always holding its shape.

Full cloth back

Caring For Your Tweed Waistcoat
To ensure your waistcoat stays sharp, hang it on a shaped hanger and allow it to air out between wears. Spot clean with a damp cloth when necessary, and dry clean for deeper care. Patience and proper care will reward you with a garment that only improves with time.
Inspired By Brendan Behan:
Inspired by the wit and wild spirit of Brendan Behan, this waistcoat channels the essence of a writer who wore his heart—and his heritage—on his sleeve. The grey herringbone weave mirrors Behan’s complexity: grounded yet expressive, classic with an undercurrent of rebellion. A garment for those who speak softly but carry a story.
