In Dawn of the Dead (1978), the Hare Krishna Monk zombie in his bright orange robes, as well as the infamously hammy Nurse Zombie.

Barbra later uses it to shoot a female zombie that clutches a baby doll under one arm.

In the 1990 remake, Ben and Barbra acquire a handgun from a zombie cop's belt holster.

The Ur-Example is the nude female model, adorned only with a morgue ID tag, who was included in Night of the Living Dead (1968).

In the chilean comic Zombies en la Moneda, one of the stories is a parody of Scooby-Doo and involves a rock band that gets lost in some underground tunnels and comes across a cavern where there are a large number of zombies in disguise, including some dressed as Michael Jackson or Elvis Presley (And some are live human beings pretending to be zombies).

and to fight a seemingly endless horde of crossed cosplayers.

This lead him to a Comiket-esque convention. Without a doubt, though, the best example of this takes place on 'The Five Bloody Fingers' arc where a Japanese young man tries to get in contact with his friends during the onset of the crossed plague in Japan. Other examples include crossed Hare Krishna monks wreaking havoc on an airport, freshly infected circus performers attacking a nearby town, a group of crossed dressed like different clerical figures (A rabbi, a catholic bishop and a nun, to name a few) hunting down 'heretics' in a desolated city. Naked infectees are also incredibly common in Crossed as well.Rick's first trip to Atlanta features several zombies with unique designs. Naked zombies can be spotted all throughout The Walking Dead, as well as zombies dressed in unique clothes like suits, bulletproof riot gear, military and even a punk attire, complete with mohawk.They would also be less likely to be taken in surprise in the early stages of said eldritch epidemic (due to superior fighting skills, senses, having fortresses, that kind of thing), and so go down fighting later on, in their fighting gear. Which makes a kind of sense - superheroes would be quick to don suits and respond to something like a zombie apocalypse.Chances are, if a superhero or villain is brought back as a zombie or something, they will be wearing their costume (or what's left of it).There were also zombie football players in Hack/Slash meets Zombies vs. One Hack/Slash arc had a slasher who resurrected a bunch of dead animals as zombies, including a circus bear in a tutu.Compare and contrast Attractive Zombie who retains both his/her personality and good looks. Distinguished from Our Zombies Are Different in that the Incongruously Dressed Zombie only looks unique functionally, it's usually (though not necessarily) your standard-issue Night of the Living Mooks drone. Not necessarily exclusive to zombies: vampires, ghosts, biped werewolves, and other human-derived monsters may also be examples of this trope, provided their outfit is unexpected and/or goofy enough to surprise and amuse the audience.

Not to mention that the horror of being attacked and zombified (or whatever) can happen right in the middle of you living your life. Their presence can also remind viewers that zombies, however mindless or indistinguishable in undeath, used to be unique, living individuals: that they're creatures to be pitied as well as dreaded. While undead in goofy outfits seldom stay on screen for long, they provide a bit of a breather for the audience, while giving the production's costumers and make-up crew a chance to exercise some creativity.
