Costume Test Montage

Someone is trying to look good for something, a date, a meeting, long-lost relative, whatever. He decides he needs to wear something special, but what?

So the character goes through a dozen different costumes in front of the mirror. He or she will often try a funny one-liner matching the costume's persona, or just as often dismiss it with a quip, usually "too butch" or "too much" (in which case the next one is "too little"). Someone else might be giving out the running commentary.

The Shopping Montage and the Makeover Montage may do something similar, but those are still fundamentally shopping sprees and makeovers. See also Fashion Shop Fashion Show, which draws on the "models on the catwalk" presentation.

Anime and Manga

 * When Sebastian in Black Butler needs to infiltrate a building as Nina the tailor's assistant, Nina refuses to let him join unless he puts on something more fashionable. Unfortunately light colors are the current trend and so nothing looks particularly good on him, not even the anachronistic Elvis jacket.

Comic Books

 * One appears in Quantum and Woody when the titular duo are trying on costumes for their new crime-fighting identities.
 * Herr Starr from Preacher has a rather hilarious montage across two pages as he tries to find something to cover up his new "urethra scalp" scar, before settling on a Panama hat.
 * Used in Arana, with an array of other people's costumes altered just enough to not get sued, in the case of things like a Wonder Woman costume (with a spider instead of a W).
 * A flashback shows Deadpool trying on a variety of costumes at a local shop that caters to the superhero crowd. He eventually settles on a black and red number with a note attached saying something along the lines of, "Thanks, but not what I'm looking for. --Your Friendly neighborhood S.M."
 * Madman did this early in his ongoing series when he switched from his initial mini-series' costume (with a full-head cowl and a sewn-shut mouth) to his more iconic look, with amusing comments about them (one covered with multi-colored circles of various sizes earned a "Wonderbread? Wunderbar!").

Music

 * Pink's music video for "Get the Party Started".

Newspaper Comics

 * Calvin and Hobbes - A Sunday strip had an "all funny sunglasses" variant. Because it was Calvin's POV, the panels were tinted the matching color and just showed Hobbes' reactions. We only see the pair he settles on in the end - which, in a case of Hilarious in Hindsight, look just like those of a certain mecha pilot.
