Joker’s Wardrobe
Aside from the aforementioned outfits, pretty much all of the Joker’s outfits come directly from the pages of a variety of comic book story arcs, from the black tux to his trademark purple coat. This is a gentle reminder that this Joker is one of the most comic book accurate adaptations we’ve seen to date. Whereas Jack Nicholson was more of a gangster and Health Ledger was an anarchist, it’s clear that this Joker is just plain insane.
Another hint these outfits give you is that they didn’t choose just one version of the Joker to create Jared Leto’s version for Suicide Squad, but that he’s rather a collection of the Jokers we’ve come across throughout the character’s time on the comic book pages. It may also be a reference to how there’s no one origin story for the Joker as made clear in The Killing Joke, but that may just be a tad far-fetched.
