Ser Duncan the Tall — known simply as Dunk — is the hulking, honourable hedge knight at the heart of HBO’s The Knight of the Seven Kingdoms. Tall, road-worn, carrying everything he owns on his back and a deep sense of what is right in his chest, he is one of the most compelling characters in the Game of Thrones universe and one of the most satisfying Halloween costumes you can build this year.
This guide breaks down all eleven pieces of the look with direct shopping links, explains who Dunk is and what makes him such a great character, and gives you the best group costume ideas — including the iconic Dunk and Egg pairing.
Full Costume Breakdown
Dunk’s look is built from eleven pieces — more than most of our guides, but each one contributes to the layered, road-worn aesthetic that makes the character immediately recognizable. Think of it as assembling a working medieval travelling kit rather than a costume.
A faded blue or olive-green medieval tunic is the foundation of Dunk’s look. It should be loose, slightly oversized, and worn-looking — Dunk is a hedge knight with no lordly income, and his clothing reflects that. Layer it over the linen shirt for the full travelling-knight silhouette.

Shop on Amazon →The greyish-green travelling cloak is Dunk’s most visually striking piece — full-length, hooded, and draped with the easy familiarity of a man who has worn it through every kind of weather. Look for a cloak in sage green, grey-green, or olive with a generous hood. The more weathered it looks, the better.
Shop on Amazon →Plain brown or dark tan medieval-style trousers complete the bottom half of the look. They should be simple, slightly tapered toward the boot, and free of any modern detailing. Dunk’s trousers are practical travelling clothes — nothing more, nothing less.
Shop on Amazon →A wide leather belt worn over the tunic defines the waist and provides the anchor point for the sword, pouch, and other carried items. Dunk wears both a main belt and a secondary rope or cord — layering two belts at slightly different heights adds the authentic hedge knight look seen in the infographic.
Shop on Amazon →Tall dark brown leather pull-on boots are essential for the full Dunk silhouette. Look for a simple design with no modern zips, buckles, or rubber soles. The boots should look like they have covered serious ground — worn, sturdy, and completely unpretentious.
Shop on Amazon →A small brown leather drawstring pouch clipped or tied to the belt is exactly the kind of practical detail that builds a believable medieval character. Dunk carries everything he owns on his person — a belt pouch is where a hedge knight keeps what little coin he has. It adds authenticity and is genuinely useful at a party.
Shop on Amazon →A wooden or tankard-style mug carried or clipped to the belt is a character-perfect prop and a very practical one for a Halloween party. Dunk is a man who appreciates a drink after a long day on the road. A plain wooden or carved mug hooked to the belt looks authentic and photographs brilliantly.
Shop on Amazon →A rolled blanket or bedroll strapped across the back or slung over one shoulder is the optional detail that completes the travelling-knight silhouette from the infographic. A military-style wool blanket rolled tightly and secured with cord or leather straps is accurate and easy to carry. Leave it at the coat check once you arrive.
Shop on Amazon →Dunk’s sword is his livelihood and his identity — a hedge knight without a sword is just a wanderer. A full-length plastic or foam longsword worn in a belt scabbard or carried openly completes the knight silhouette immediately. Look for a plain, functional design rather than anything ornate — Dunk’s equipment is practical, not decorative.
Shop on Amazon →Dunk’s shield — plain, battered, and bearing a simple elm tree device — is one of his most iconic props. A plain wooden or plastic shield is the base; paint a simple tree on the front for full accuracy, or leave it plain for a quicker assembly. Carried on the back or on one arm, it makes every photo look perfect.
Shop on Amazon →Weathering the Costume
Dunk has been on the road for years. Lightly distress the tunic and trousers with brown eyeshadow or diluted brown paint around the hems, knees, and elbows. A costume that looks like it has seen real use always reads as more intentional than one that looks fresh from a box. The cloak in particular benefits from a little weathering at the edges.
Who Is Ser Duncan the Tall?
Ser Duncan the Tall — universally known as Dunk — is a hedge knight of no particular birth or fortune, wandering the Seven Kingdoms a century before the events of Game of Thrones. He appears in George R.R. Martin’s beloved Tales of Dunk and Egg novellas, three long stories that have been acclaimed as some of the finest writing in Martin’s entire Westerosi canon.
In HBO’s 2025 adaptation The Knight of the Seven Kingdoms, Dunk is brought to screen as a towering, earnest young knight trying to live by a code of honour in a world that doesn’t always reward it. He takes the young prince Egg as his squire without knowing who Egg really is — and the journey that follows becomes one of the warmest, most human stories in the entire Game of Thrones universe.

Why It Works as a Halloween Costume
The Dunk costume works on every level. For fans of the show or the novellas, the combination of the green cloak, the sword, and the shield is immediately recognizable. For everyone else, it reads as an excellently assembled medieval knight costume with clear visual coherence and obvious effort behind it. It is also a genuinely impressive physical costume — the layered clothing, the weapons, and the bedroll create a silhouette that fills a room.
Couples & Group Costume Ideas
Dunk is almost never alone in the source material — his partnership with Egg is at the heart of everything. Here are the best ways to build a group costume around him.
Best Couples Costume: Dunk & Egg
Dunk and Egg are one of the great duos in fantasy literature — the enormous, honourable hedge knight and his small, sharp, secretly royal squire. The contrast in height, energy, and costume complexity between the two makes this one of the most visually interesting couples costumes available right now. Check out our full Egg Costume Guide for a complete breakdown of his look.
Full Westerosi Travelling Party (Group of 4–6)
Green cloak, sword, shield, wooden mug. The full guide above.
Bald cap, brown tunic, grey cloak, wooden bowl. Quietly watchful.
Bright surcoat, costume armour, a favour tied to the arm. Confident.
Worn patched armour, tired expression, very little coin left.
Grey robes, white head covering, seven-pointed star pendant.
Plain rough linen, earthy tones, minimal accessories. Dignified.
Dunk & Brienne of Tarth (Knights of Honour)
For a couples costume that spans the entire saga, pair Dunk with Brienne of Tarth — blue armour, Oathkeeper sword, and the same stubborn commitment to honour that defines Dunk himself. Two of Westeros’s most principled knights, a century apart, side by side. Any serious Game of Thrones fan will love it.
Final Tips for Wearing the Look
Dunk is a character defined by physical presence and quiet moral weight. A few notes on making the costume land at its very best:
- Layer Properly The linen shirt under the tunic under the cloak is what gives the costume its visual depth. Don’t skip the base layer — the visible collar and cuffs beneath the tunic are a key part of the authentic medieval look.
- Carry the Shield on Your Back When you’re not actively posing for photos, wear the shield strapped across your back rather than on your arm. It’s more comfortable, keeps your hands free, and looks exactly like a knight who has been carrying it all day.
- Use the Mug The wooden mug is both prop and practical item. Fill it, carry it openly, and you have the perfect Dunk energy all evening — a man at ease after a long day on the road, drinking something well-earned.
- Weather Everything Brown eyeshadow lightly rubbed into hems, knees, and elbows transforms a new costume into a worn one in five minutes. Don’t skip this step — the difference it makes is significant.
- Move with Purpose Dunk doesn’t hurry unless he has to. He moves slowly, deliberately, and with the easy confidence of a very large man who has never had to worry about being overlooked. That physical presence is free and it makes the costume.
