Halloween Costume Guide
He died 5,747 times for this look. The least you can do is wear the hat right.
Teddy Flood arrives on the train to Sweetwater at the start of every loop, tips his hat to Dolores, and gets shot before the episode ends. He is a host programmed as Westworld’s archetypal hero gunslinger, protective of Dolores Abernathy and largely unaware that his life resets. He is played by James Marsden and appears as a main character in Seasons 1 and 2 of the HBO series (Westworld Wiki). The costume is a straightforward western build with enough specific details to read as Teddy rather than a generic cowboy, particularly at a Westworld group event.

The hat angle matters more than any other single adjustment in this build. Teddy wears his level and with intent, not tilted back, not cocked to the side. A hat worn wrong on a western costume reads as a party prop on someone who put it on at the door. Get it set before you leave the house, check it in a mirror, and leave it there. The holster also needs to be adjusted before the party, not at it. If the belt rides too low or the revolver shifts out of reach, you spend the night fidgeting with it.
Teddy spends most of the first two seasons doing the same thing: arriving in Sweetwater, finding Dolores, and getting killed before anything changes. He is patient about it in a way that is clearly not a choice, and then in Season 2 he finally has a moment where it is a choice, and he makes the wrong one, and that is the whole character. At a party, the version of Teddy worth playing is the one from the first season: steady, quiet, slightly out of place in every room.
Wool hat versus straw hat
A straw cowboy hat is a summer hat. At an indoor Halloween party in autumn, it will read as beach costume before it reads as Westworld. The wool hat in the item list has the weight and shape that works year-round and looks like it belongs to someone rather than having been bought for the occasion. The price difference between a cheap straw hat and a decent wool one is real, but the read is completely different.
The revolver is a prop, not a weapon
Confirm your venue allows toy props before showing up with a holstered revolver. Some indoor venues have policies against realistic-looking firearms, even obviously plastic ones. Check before the party, not at the door. If props are not allowed, the holster belt still works empty and still reads as the character.
Group Idea: Westworld Cast
Excellent group for anyone going to a sci-fi or TV fan event. Teddy, Dolores, Maeve, and the Man in Black cover the four most visually recognizable characters from the show, and each costume reads on its own without needing the others for context. At a general party, Dolores’s blue prairie dress and the Man in Black’s all-black look carry the most immediate recognition. Teddy benefits from being in the group rather than standing alone.
Group Idea: Western Genre
Strong group for a crowd that plays western games or watches western films. Arthur Morgan and John Marston have very high recognition among gamers. Django is widely known. Teddy sits slightly more niche in this group because he is the only one from a TV show rather than a film or game. Visually the group works well since all four costumes share the same era and silhouette, and the contrast between characters with very different moral codes gives the group something to talk about.
Group Idea: Same Actor
Might work, but only if everyone in the group is confident enough in their costume to carry recognition alone. Cyclops has a defined visual. Prince Edward from Enchanted has a defined visual. Tom Wachowski from Sonic is a plain-clothes sheriff, which is hard to distinguish from a regular person at a party. Teddy is a cowboy. The concept rewards people who know Marsden’s career well, and requires everyone to commit to a character that can stand without the others explaining it.
Group Idea: Same Name
Might work, but the concept asks the crowd to connect four characters by a shared name variant, which is a lot to expect at a loud party. Ted Lasso has the strongest current recognition by a wide margin. Ted Wheeler from Stranger Things is well known. Theodore “Ted” Logan from Bill and Ted is a classic. Teddy Flood is the most niche of the four. The group works best if someone in it is willing to explain the concept, and is willing to explain it repeatedly.
Group Idea: Niche Sci-Fi
Might work, but this group requires a convention crowd or a very specific friend group to land. Officer K, Vision, and the T-1000 all have distinct visual reads. Teddy is the least obviously artificial of the four since his look is a plain western costume with no futuristic elements. The group concept is coherent, beings who were built to serve a purpose and either escaped it or exceeded it, but that depth is lost on anyone who does not know all four characters.
This is one of the more closet-friendly builds in western costuming. Most of the clothing items are things that exist in real wardrobes. The specialist purchases are the hat, the holster belt, and the boots.
Teddy is the character everyone trusts immediately and no one fully understands. He is polite, composed, and slightly too gallant for the situation he is in. That is easy to play for a few hours.
The wool cowboy hat is the single item that makes this costume read as Teddy rather than a generic western look. Layer a tweed vest over a linen shirt, add cowboy cut jeans, Toloni boots with spurs, and a leather gun holster belt. The cashmere scarf adds the finishing period detail.
Teddy is the least immediately recognizable of the main Westworld cast for a general Halloween party in 2026. The show was cancelled and pulled from HBO Max, and Teddy’s look is close enough to a plain western cowboy that most people will read it as “cowboy costume” rather than specifically Teddy Flood. If you are going as part of a Westworld group, he makes the group immediately stronger. Solo, you will need someone to ask before the character lands.
Three quotes capture him well. The most romantic: “No matter what happens, no matter how I change, or how much you change me, you’re my cornerstone.” The most used to describe the whole show: “That’s the thing about this world, you know? Some of the most unbelievable things turn out to be true. And the things that feel the most real are nothing but stories that we tell ourselves.” And the simplest, said to Dolores: “Where we go, we go eyes open. Together.”
Teddy Flood is played by James Marsden. He appeared as a main cast member in Seasons 1 and 2, returned briefly in Season 4, and was absent from Season 3. Marsden is also known for playing Scott Summers/Cyclops in the X-Men films, Prince Edward in Enchanted, and Tom Wachowski in the Sonic the Hedgehog movies (IMDb).
Teddy is a host, one of the android inhabitants of the Westworld theme park. He was originally programmed as a gunslinger protecting Dolores Abernathy as part of his narrative loop. He was not given a backstory until Robert Ford added one involving a character named Wyatt. Teddy eventually gains awareness and chooses to end his own loop rather than continue under Dolores’s altered programming.
According to the show, Teddy died 5,747 times, more than any other host in the park. He was regularly used as target practice and plot device in his loop, dying and resetting without memory of any of it. That number is the show’s way of making his eventual awareness land harder.
Yes, and it is one of the better reasons to use it. If you own boots, jeans, and any kind of vest or jacket, the main additions are the cowboy hat and the holster belt. The scarf and spurs are optional details. This is a build where your existing wardrobe can do most of the work.
The Sweetwater group with Dolores, Maeve, and the Man in Black is the most recognizable combination. Teddy and Dolores as a couple also works well on its own. Both options benefit from having Dolores in the group, since her blue prairie dress is the most immediately iconic visual in the show and anchors recognition for the rest of the group.
