Thanks everyone who contributed to this thread! I've been putting together a Leto Joker costume and wanted to post up my (very minor) work that maybe someone could use.
I am doing the Arkham escape costume as I love the shirtless-open-jacket look but I dislike the boxers/bat tights/boots outfit from later in the film.
I first dismissed the Hot Topic jacket but after seeing it in the store, I felt that it had potential. Especially for the price - the fake grain texture is actually pretty good and the coat is a good size as well. I took the idea mentioned earlier in this thread of coating the jacket with a pearalescent material, and here's my result.
First, the stock image of the jacket. Good texture and proportions but the color is flat.

I experimented with a number of paints, but here's what eventually worked:

DecoArt Amethyst Metallic acrylic paint
Anita's Metallic "Deep Plum" acrylic paint
Textile medium
Mixing the paint & textile medium 2:1 turns the acrylic paint into permanent fabric paint.

I began lightly sponging it on in a hidden area and it looked pretty good so I started working it along one front panel

I let the first section dry, and as it dried it looked even more vibrant! I ended up sponging on an even amount over the entire coat. The color is translucent enough that the original maroon of the jacket comes through in the light, along with the amethyst and it definitely changes as I move. I'm incredibly happy with the result, especially for not having to pay hundreds for a custom made Joker trench.

And a quick test (don't mind the hair, it was just a practice run!) The lighting was terrible in the bathroom but you can see the color change from the top of the coat to the bottom depending on how much light is hitting it.
