Dress-Up Episode

More commonly (but not exclusively) seen in visual media like television and comics, the modern protagonists of the work in question suddenly and inexplicably need to dress as if it's the Victorian Era. It could be that they have to attend a Masquerade Ball without attracting attention to themselves, or that trace amounts of Time Travel have suddenly and inexplicably thrown them back to The Wild West. Maybe they have to establish diplomatic relations with an alien race that is convinced they live in the 1920s. Whatever the reason, the main characters of the work dress up in recognizable, elaborate or anachronistic costumes that they wouldn't otherwise wear.

Note that while examples of this trope are predominantly historical costumes, time travel is not a requisite. It's any time the main characters dress in costume for the duration of an episode/scene/whatever, usually in order to blend in or detract suspicion.

Is separate from, but may overlap, Halloween Episode. Related to Costume Porn and applicable to Going Native. Compare Changed My Jumper.

  • Doctor Who. Since the entire premise of the show is based on time travel, this is pretty much a given. Most of the time, however, they don't even bother with this, and the Doctor himself rarely changes his garb, but some episodes has the Doctor's companion dress up, such as when Rose dressed in '50s style clothing and Donna dressed like a flapper in the '20s. On one occasion, both Clara and the Doctor dressed to the nines, 1920s style, for a trip aboard a spaceship replica of the Orient Express.
  • In the episode "The Affair at the Victory Ball", Poirot and Hastings are invited to a fancy-dress (masquerade) ball and told to come as "someone famous". Poirot comes as himself.
  • Happens all the time on Supernatural. In one episode, "Frontierland", Dean wears a cheesy cowboy costume, and is made fun of because it looks nothing like how the people actually dress.
  • A season 6 episode of Castle requires the entire cast to dress and act like it's The '70s for most of the episode, in order to not confuse a witness who thinks it's still 1978.
