Halloween Costume Guide
The man behind the throne. Never on it. Always in control of who is.
Otto Hightower serves as Hand of the King to Viserys I Targaryen and spends most of his screen time engineering a succession that benefits his family. He is calm, deliberate, and almost never wrong about how a situation will unfold, which makes him easy to dislike and difficult to dismiss. He is played by Rhys Ifans in the HBO series House of the Dragon, which premiered in 2022 as a prequel to Game of Thrones (Wikipedia). The Hand of the King pin is the one item that separates this from a generic medieval advisor build, and without it the costume has no anchor.

The Hand of the King pin needs to be pinned at chest height and visible the moment anyone looks at you. If it gets buried under the scarf, or if the scarf keeps sliding over it, fix that before you leave the house. The entire recognition chain depends on someone seeing that pin and knowing what it is. If it is hidden, what you have is a man in dark layers, and that is not a specific enough costume to survive a crowded party.
Otto sits through every scene like a man who has already worked out how it ends. He does not react to surprises because he does not have many of them. He is the person at the Small Council table who finishes his thoughts completely before anyone else has started theirs. That patience is the character at the party.
Pin the brooch so it cannot shift
The Hand of the King pin is a brooch, and brooches move. After an hour at a party, it will have migrated or flipped sideways. Before you go out, test it on the actual fabric you plan to wear it on. If the fabric is too loose or knit, the pin will pull and tilt. Back it with a small piece of felt or a second pin on the underside to keep it flat and stable. This is the one item you actually need to stay in place all night.
The scarf is the layer most likely to look wrong
A soft scarf draped over a sweatshirt can look like you forgot to take it off when you came inside, rather than a deliberate costume choice. The difference is how it sits: let it fall off one shoulder slightly rather than sitting perfectly centered. A slightly uneven drape reads as deliberate layering. A centered, tidy scarf reads as cold-weather accessory.
Group Idea: The Green Council
Strong group for people who have watched the show. The Green Council is the faction that backs Aegon’s claim over Rhaenyra’s, and Otto is the architect of it. Alicent and Viserys are the two people he spends the most time managing. The dynamic is visible on screen and in costume: Otto is dark and controlled, Alicent is formal and strained, Viserys is increasingly unwell. At a general party the group may need context. At a Game of Thrones or House of the Dragon watch party, it lands without explanation.
Group Idea: Power-Hungry Fantasy Royals and Advisors
Excellent visual group because every costume is immediately readable on its own and the shared concept — people who want power more than they want peace — is legible without the costumes explaining it. Cersei and Tyrion are among the most recognized TV characters of the last decade. Farquaad lands at a family-friendly event and reads even without context. Otto is the weakest link on name recognition, which the Hand of the King pin partially compensates for.
Group Idea: The Rhys Ifans Roster
Might work, but only if everyone in the group knows the actor well enough to commit. Xenophilius Lovegood is visually distinctive and Harry Potter recognition is broad. Rasputin from The King’s Man is niche. The Lizard requires a proper costume, not just a suggestion of one. Otto is the least visual of the four. This concept is interesting to anyone who spots the through-line and confusing to everyone else. Works best if the group introduces themselves as “same actor, different roles” so people have a frame for it.
Group Idea: The Otto Syndicate
Might work, but this is a concept that has to be explained at every conversation, which is either the point or the problem depending on your group. Doctor Octopus is well-known. Otto from The Simpsons is easy to put together. A Man Called Otto is a recent film with a specific demographic. Otto Hightower is the most visually elaborate of the four. The shared name is the gag and the costumes are very different from each other, which is actually part of what makes it work visually.
Group Idea: Ruthless Masterminds and Strategists
Strong group on visual contrast: four very different aesthetics anchored by the same personality type. Thomas Shelby and Gus Fring carry the broadest recognition. Marty Byrde is niche outside of Ozark viewers. Otto is the historical outlier in modern company, which is either a problem or an interesting tension depending on how you frame it. This group rewards people who follow prestige drama and is invisible to everyone else.
Most of this build comes from items people already own or can find at a thrift store. The only thing you actually need to buy is the Hand of the King pin. Everything else is dark layering that most wardrobes can approximate.
Otto is not theatrical. He does not perform. He finishes his sentences and waits for other people to catch up. That is the whole character in one note.
The Hand of the King pin is the item that identifies the costume. Start with a dark pullover or shawl-collar sweatshirt as the base, layer a soft scarf or wrap over it, and pin the Hand of the King brooch at the chest. Bronze buttons and a leather cord layered over the front panel push the tunic silhouette further. A Cuban link chain necklace adds the weight of office. Keep everything dark and layered.
House of the Dragon Season 2 aired in 2024, which keeps the show in recent memory, but Otto’s recognition drops sharply outside of people who actively follow the series. The Hand of the King pin does a lot of work for viewers who know it. Without it, the costume reads as generic medieval advisor.
Two quotes define him. The first captures his political philosophy: “The King sees what he wishes to see. That is a King’s prerogative.” The second is more direct about what he actually values: “I have served four kings faithfully. I will not apologize for placing the realm above sentiment.”
Otto Hightower is played by Rhys Ifans, a Welsh actor. He is also known for playing Dr. Curt Connors in The Amazing Spider-Man (2012), Xenophilius Lovegood in Harry Potter and the Deathly Hallows (2010), and Grigori Rasputin in The King’s Man (2021) (IMDb).
The Hand of the King is the most powerful position in the realm after the throne. The Hand manages the Small Council, handles the daily business of government, and acts in the King’s name when the King is unavailable. Otto holds the position twice across the series and uses it primarily to position his family’s claim to the succession.
Cut down to four: dark pullover, scarf, Hand of the King pin, and one necklace. The bronze buttons and leather cord are for people who want the layered tunic front. The second pullover option is an alternative base, not an addition. Pick one base layer and build from there.
No. Without the pin, this is a man in dark medieval layers. The Hand of the King brooch is the single identifying element. Everything else in the build supports it.
