#OneChicago is celebrating spooky season — well, some members of the franchise are.
Wednesday’s episodes of “Chicago Fire” and “Med” will see several characters dressing up in Halloween garb, so TVLine is hosting an official costume contest for the participating parties. But before we evaluate the specifics of the looks, let’s get into what’s to come in each #OneChicago episode during Halloween week.
In “Chicago Med,” ominously titled “What’s Hiding in the Dark,” a personal clash between Asher and Archer reaches its breaking point. (Oh baby, we wonder what that could be about?!) Meanwhile, Charles and Ripley diagnose a patient with a rare neurological disorder, and Goodwin’s personal life gets put to the test. Plus, according to the photos below, Ripley and Sadie go trick-or-treating!
Per usual, “Chicago Fire” follows “Med,” this time with an episode titled “Ghosts,” which finds Cruz hunting for the identity of an unknown ally. (Mysterious!) The logline reveals “Mouch will take steps to help a friend,” and the episodic stills below show those steps include a fundraiser hosted at Molly’s to help the Herrmann family after their Episode 4 house fire. Elsewhere, Vasquez will be forced to make a difficult choice.
Despite Jason Beghe’s previous pitch to dress up in a gown to win Chapman back, “P.D.” isn’t getting spooky this year. The Intelligence Unit is too busy dealing with the aftermath of a bombing that rocks downtown Chicago. Plus, the episode titled “Miami” will see Atwater reuniting with an old friend from his academy days.
Now that we’ve established some context for #OneChicago’s block of episodes next Wednesday, let’s get to the judging! Scroll through the photos below of each Halloween costume, then pick your winner in our poll below.
Sadie and Ripley as Piglet and Tigger, Chicago Med

First up, we’ve got Sadie and Ripley, who we know are spending a lot of time together as of late. (Ripley is spending so much time with his girlfriend, in fact, that he offered his vacant apartment to Frost in last week’s episode!) From the looks of it, these two are taking Emelia and a whole gaggle of girls trick-or-treating.
While Sadie and Ripley look awfully cute, if we really want to get critical in this very official contest, these costumes are pretty low-effort. Any one of us could snag a Winnie the Pooh-themed onesie from Amazon the day before Halloween; it’s an ideal last-minute look. Some face paint could’ve really gone a long way in taking this get-up to the next level. That being said, their costumes are very practical — they’ve got children to keep up with!

Because these photos come with no context, we can only guess that Mouch is going for an old-timey saloon owner in honor of his bar-owning pal Herrmann, and he is nailing it! He’s going full Wild West on this Midwestern front. Plus, check out that mustache? There’s something so chic about a man in a mustache, and that thing is groomed within an inch of its life.
Now onto his garb. As a girl who grew up reading too much Seventeen Magazine, I know the importance of an outfit that can go day-to-night, and by the looks of it, so does Mouch. This is the perfect low-key costume, that still screams, “I thought about this before today.” It’s details like that little black bow and the perfectly placed arm cinches that deserve appreciation in a contest like this. And we wouldn’t leave without holding for applause for that vintage felt hat — claps all around!
