🥚
Quick Answer: To dress like Egg, you need a bald cap and a dark hooded cape. Those two items are what make this specifically Egg rather than any medieval squire.
  • Bald cap (essential)
  • Dark hooded cape (essential)
  • Brown medieval linen shirt
  • Leather belt with wooden practice sword
  • Brown medieval boots

Egg spends A Knight of the Seven Kingdoms keeping his hood up and his name short, travelling across Westeros as a squire while being a Targaryen prince. The Tales of Dunk and Egg are George R.R. Martin’s novellas that the HBO series is based on, set roughly a century before Game of Thrones. The bald cap is the one purchase this costume cannot do without. Recognition outside fans of the show is limited, so the costume works best paired with someone as Dunk.

  • 1 Medieval Linen ShirtBrown linen-style pullover, worn slightly loose and untucked. Any fitted or tailored shirt reads wrong here. Egg is dressed to disappear, not to be noticed.

  • 2 Medieval Hooded CapeDark floor-length hooded travel cloak. The hood is the costume’s only interactive prop: it goes up when Egg is concealing his identity, down when he drops the pretense. That one movement is the whole in-character performance.

  • 3 Wooden Practice SwordSquires carry practice weapons, not steel. This detail matters to anyone who knows the show and tells everyone else what role this person plays in the hierarchy.

  • 4 Medieval Leather BeltBrown leather worn at the waist to hold the wooden sword. Check your wardrobe first; any plain brown belt does the job.

  • 5 Bald CapThe essential item. Without it, the brown shirt, dark cape, and wooden sword are a generic medieval squire costume. The bald Targaryen head is the only thing that makes this specifically Egg. Apply it before anything else, smooth the edges carefully, and blend with foundation. A bad edge ruins the whole effect.

  • 6 Medieval BootsBrown tall boots, practical and worn-looking. Check your wardrobe; any tall dark boot works fine.

How to Style the Egg Halloween Costume

The bald cap is the first thing people look at, and if the edge is visible at the hairline the costume immediately reads as a costume rather than a character. Getting the blend right before the cape goes on is the only thing that matters in the assembly. The specific failure at a party is pulling the hood down too early. The reveal only works once per person. Keep it up when you arrive, drop it when someone asks who you are. If they still don’t know, that tells you something useful about the crowd.

There is a moment in the show where Egg is asked his name directly and says simply “Egg,” with no explanation and no apology for the brevity. He has been a prince his whole life and this is the one word he chose for himself. That is the whole character.

Bald cap edges lift after two hours

Spirit gum at the hairline holds the front edge in place through a full party. Without it, body heat and movement cause the edge to peel away from the skin by mid-evening, which reads as a malfunctioning prop rather than a Targaryen trait. Apply it before the foundation blend, not after. Bring a small mirror so you can check the back edge occasionally; that is where lifting starts first.

Hood up is the default, not the reveal

Most people wear the hood down and treat the bald cap as the main event. Egg spends most of the show with his hood up, which means the bald head is what you reveal when someone earns it. Arriving with the hood up and dropping it in response to “who are you supposed to be?” generates a more specific character moment than just walking in bald from the start.

Egg Group Halloween Costume Ideas

The Essential Duo

Egg and Ser Duncan the Tall

Strong pairing for fans of the show. The size contrast between the small bald squire and the towering hedge knight makes the relationship readable at a glance, and the two costumes are visually distinct enough that they do not compete. Outside the show’s fanbase the duo is not yet widely known, so this works best at events where people have seen A Knight of the Seven Kingdoms.

Targaryen Dynasty Group

Egg, Daemon Targaryen, Rhaenyra Targaryen

Conditional group spanning three HBO series. Each character is from a different era of the same bloodline, which is the conceptual thread, but Egg’s squire clothing sits far enough from Daemon’s armour and Rhaenyra’s court dress that the group needs explanation to land as a unit rather than three separate medieval costumes. Works at events where people know all three shows.

Egg Halloween Costume DIY Tips

What to Buy and What to Skip

Four of these six pieces are things most people already own or can find at a thrift store. Two require dedicated purchases.

  • Bald cap: buy this first, it is the only non-substitutable item
  • Wooden practice sword: buy this, it establishes the squire role specifically
  • Brown linen shirt: any loose brown shirt from your wardrobe works
  • Dark hooded cape: any dark full-length hooded cloak or coat; thrift stores reliably stock these before Halloween
  • Brown belt: any plain brown leather or faux-leather belt
  • Brown boots: tall dark boots are common enough in most wardrobes; only buy if you genuinely have nothing close

Bald Cap Application Notes

A silicone or latex bald cap in a pale warm skin tone is the most convincing option. Avoid caps that are too pink or too grey against your skin. The application matters as much as the cap itself.

  • Apply to clean, product-free hair; any product underneath causes slipping
  • Work from front to back, pressing firmly as you go
  • Blend the front hairline edge with foundation in your skin tone
  • Set the blended edge with powder so foundation does not transfer
  • Spirit gum at the hairline holds lifting edges through a full evening
  • Check the back edge periodically; that is where lifting starts first

Egg Halloween Costume: FAQ

Six pieces: brown medieval linen shirt, dark hooded travel cape, wooden practice sword on a leather belt, bald cap, and brown medieval boots. The bald cap and hooded cape are the two essential items. Without the bald cap, the costume reads as a generic medieval squire. Without the hood, you lose the one in-character moment the costume has.

Egg’s defining gesture is introducing himself only as “Egg” and declining to elaborate. He is Aegon Targaryen, a prince who chose a single syllable over his full name and title for years on the road. For in-character delivery: say “Egg,” offer the small smile that goes with it, and do not say anything more.

Among fans of A Knight of the Seven Kingdoms it works well, but the show is not yet as widely known as Game of Thrones or House of the Dragon, so recognition at a general party will be limited. It is a better choice paired with someone as Ser Duncan the Tall. The size contrast between the two costumes communicates the relationship even to people who have not seen the series.

Egg is the nickname of Aegon V Targaryen, a young prince who disguises himself as a common squire and travels with the hedge knight Ser Duncan the Tall in HBO’s A Knight of the Seven Kingdoms. Portrayed by Dexter Sol Ansell, Egg is bald, a Targaryen trait, and wears simple medieval squire clothing to conceal his royal identity. He is based on the character from George R.R. Martin’s Tales of Dunk and Egg novellas, set roughly a century before Game of Thrones.

Egg wears simple, practical medieval squire clothing: a brown linen shirt, a dark hooded travel cape, a leather belt with a wooden sword at the hip, and brown medieval boots. His most distinctive feature is his bald head, which he frequently conceals under his hood to hide his Targaryen identity while travelling with Dunk.

Egg is portrayed by Dexter Sol Ansell in HBO’s A Knight of the Seven Kingdoms. The character is Aegon Targaryen, who will eventually become King Aegon V. The series follows his travels with Ser Duncan the Tall across Westeros approximately a century before Game of Thrones.

Ser Duncan the Tall is the obvious choice. The size contrast between the small bald squire and the towering hedge knight communicates the relationship even to people who have not seen the show. For a wider group, Daemon Targaryen and Rhaenyra Targaryen from House of the Dragon extend it into a multi-series Targaryen dynasty concept.
