Umbrella Academy has a lot of great looks thanks to the era jumping and tome travel elements on the show. Previously we broke down how to put together looks from Allison and Klaus.
Stranger Things
Season 4 of Stranger Things gave us PLENTY of group costume options. We have a Hellfire Club break down here as well as a Max Mayfield outfit breakdown here. There is also a Quicksilver clothing line inspired by the show. Many of the looks that Argyle is seen wearing on the show are available for purchase, as are outfits inspired by other cast members.
We’ve done breakdowns on Butcher and Frenchie’s outfits in the past. Putting together a cosplay for most of these characters is almost a closet cosplay. MM and Hughie are well known for the T-shirts they wear on the show and there are tons of options.
Look. I don’t know how this is geeky, but I also don’t know how it is not. T-rex inflatable costumes are awesome. Get the Spiderman and Venom-inspired T-Rex costumes here.
The geeky clothing brand, Her Universe, makes a green cargo jacket inspired by the one worn by Kamala Kahan on Ms. Marvel. You can also find variations of the shirts she wears online. Her Ladies get Information shirt and some of the other tee she wears are available rom different vendors online. The red Dagger charcater is probably the most recognizable among the costumes worn by her friends.
DC Comics characters reimagined in a 1940s-era pin-up art style. Simplicity offers a DC Comics Bombshells Costume Sewing Pattern if you wanna try your hand at making the costumes yourself.
Gotham Knights
The Gotham Knights video game reveal trailer shows the game’s main antagonists will be the Court of Owls, created by heavyweight comics duo Scott Snyder and Greg Capullo, the former of which consulted on the game’s depiction of the legendary villains. Gotham Knights features four playable heroes: Batgirl, Nightwing, Red Hood, and Robin (Tim Drake).

WandaVision
WandaVision was a nod to and a blend of classic television and the Marvel Cinematic Universe in which Wanda Maximoff (Elizabeth Olsen) and Vision (Paul Bettany)—two super-powered beings living idealized suburban lives—begin to suspect that everything is not as it seems. This series has plenty of Halloween inspiration to draw from and a large array of characters, from different decades with tons of different costume options.
