Egg — the bald, wide-eyed young squire from HBO’s The Knight of the Seven Kingdoms — is one of the most quietly compelling costume choices of 2025. Simple, immediately recognizable to fans of the show, and genuinely comfortable to wear all evening, it’s the rare Halloween costume that relies entirely on atmosphere rather than elaborate props.
This guide breaks down every piece of the look with direct shopping links, explains who Egg is and why the show matters, and gives you the best group costume ideas for building a full Westerosi ensemble with friends.
Full Costume Breakdown
Egg’s look is defined by its deliberate simplicity — a young boy from a noble house disguising himself as a commoner’s squire. Every piece is humble, worn, and functional. That restraint is exactly what makes it striking.
A simple brown or olive linen tunic is the foundation of Egg’s entire look. It should be loose-fitting, plain, and slightly worn-looking — nothing ornate, no embroidery, no embellishment. Egg is travelling as a commoner and every piece of his clothing reflects that deliberate humility.

A full-length hooded cape in charcoal or dark grey, worn loosely over the tunic, creates the silhouette seen throughout the show. Look for one with a natural drape and simple closure.
Shop on Amazon →Egg’s shaved head is his single most iconic visual trait — the detail that gives the character his nickname and immediately distinguishes him from every other medieval squire. A flesh-toned latex bald cap, blended carefully at the edges with makeup, is the essential finishing touch that makes the whole costume click.
Shop on Amazon →A simple rope or thin leather belt tied around the waist of the tunic is both accurate and practical — it defines the silhouette and keeps the tunic from looking shapeless. A rough-textured leather strip or braided rope in brown or tan works perfectly. Keep it simple and avoid any metal buckles that look too modern.
Shop on Amazon →Dark brown medieval-style pull-on boots with a low heel and simple stitching complete the bottom half of the look. Avoid anything with zips, buckles, or modern soles — the more worn and plain the better. Genuine leather or convincing faux-leather options both work well for the costume.
Shop on Amazon →A wooden bowl and eating utensils carried as props are a perfect character-accurate detail — the kind of thing a travelling squire would carry on the road. They’re immediately funny in the context of a Halloween party and make for a great conversation starter and photo prop. Tuck them into the belt or carry the bowl openly.
Shop on Amazon →A wooden practice sword tucked into the belt is an optional but excellent prop — Egg is a squire in training, and a training sword is exactly what he would carry. A simple wooden or foam sword in natural brown adds instant recognition for fans and makes the costume read as “medieval squire” to everyone else.

The infographic highlights four finishing details that take the costume from good to excellent: a simple cloak fastener at the neck (a plain metal ring or toggle), intentional dirt and weathering on the tunic using brown eyeshadow or fabric paint, keeping accessories minimal throughout, and above all maintaining that young and humble expression that defines Egg’s presence in every scene. These details cost nothing but make an enormous difference.
Applying the Bald Cap
The bald cap is the most technically demanding part of the costume but is very manageable with a little preparation. Apply spirit gum or skin-safe adhesive around the hairline, stretch the cap over the head, and blend the edges with latex or skin-coloured makeup. Setting powder over the top prevents shine and makes the transition from cap to skin look seamless. Practice once before the night itself.
Who Is Egg?
“Egg” is the nickname of Aegon Targaryen — a young prince of the Targaryen dynasty who shaves his head and travels incognito as the squire of Ser Duncan the Tall, a wandering hedge knight of no particular rank or fame. The character appears in George R.R. Martin’s Tales of Dunk and Egg novellas, set roughly a century before the events of Game of Thrones.
In HBO’s 2025 television adaptation The Knight of the Seven Kingdoms, Egg is brought to screen as a wide-eyed, quietly determined boy navigating a world of tournaments, politics, and honour — doing his best to understand what it means to be both a prince and a person, stripped of the titles that would usually define him.

Why It Works as a Halloween Costume
The Egg costume works on two levels simultaneously. For fans of the show or Martin’s novellas, it is an immediate and warm recognition moment — the bald cap alone is enough. For everyone else, it reads as a beautifully put-together medieval fantasy costume with a clear, coherent visual identity. It is also one of the most comfortable Halloween costumes you can wear — loose linen, soft boots, and a cloak are genuinely pleasant for a long evening.
Couples & Group Costume Ideas
Egg is almost always paired with Ser Duncan the Tall in the source material, which makes this one of the most natural couples costumes in the Game of Thrones universe. Here are the best ways to bring others along.
Best Couples Costume: Egg & Ser Duncan the Tall
Dunk and Egg are one of the great partnerships in Martin’s writing — the towering, honourable hedge knight and his small, sharp, secretly royal squire. Ser Duncan’s costume requires a simple knight’s tabard or surcoat in muted colours, chainmail (real or costume), a sword, and a battered shield. The size contrast between the two characters makes the pairing immediately funny and immediately recognizable.
Full Westerosi Travelling Party (Group of 4–6)
Bald cap, brown tunic, grey cloak, wooden bowl. The full guide above.
Knight’s tabard, costume chainmail, sword and shield. Towering, honourable energy.
Worn armour, patched surcoat, tired expression. Travelling on a shoestring.
Grey robes, white head covering, seven-pointed star pendant. Quiet authority.
Bright surcoat, polished costume armour, a favour tied to the arm.
Plain rough linen, earthy tones, minimal accessories. Struggling but dignified.
Egg & Daenerys (Targaryen Through the Ages)
For a couples costume that spans the entire Targaryen saga, pair Egg with a Daenerys costume — platinum wig, dragon-scale dress, and a small dragon prop. Both are Targaryens, both are iconic, and the contrast between Egg’s humble travelling clothes and Daenerys’s regal presence makes for a genuinely interesting visual pairing.
Final Tips for Wearing the Look
Egg is a character defined by quiet intensity and deliberate simplicity. A few notes on making the costume land at its best:
- Weather the Costume Egg has been on the road. Lightly distress the tunic with brown eyeshadow or diluted brown paint around the hem, cuffs, and elbows. A costume that looks slightly worn always reads as more intentional than one that looks brand new.
- Blend the Bald Cap Carefully The edges of the bald cap are the make-or-break detail. Take time to blend them properly with makeup — a seamless transition from cap to skin is what separates a convincing costume from an obvious one. Setting spray helps it last all evening.
- Carry the Bowl Openly The wooden bowl is both prop and conversation starter. Carry it openly rather than hiding it away — it immediately signals the character to fans and adds a fun, slightly absurd detail for everyone else.
- Keep Accessories Minimal As the infographic notes, minimal accessories are part of the character. Resist the temptation to add things. Egg’s power is in what he doesn’t have on him.
- The Expression Is Everything Egg watches everything. He is always slightly ahead of what’s being said, always processing. A look of quiet, attentive intelligence — not blank, not aggressive, just watchful — is the character’s defining quality and costs nothing to wear.
