Comic book featured costumes have been a significant source to don into the looks of characters from the comic books. For more than decades, they probably are the only ones whose devotees increased most dramatically and are still growing. If you are already a part of its fandom, then you would already know about the Harley Quinn Costume Jacket, and much of it is praised by all the comic nerds all over the world and besides that, there is absolutely no other character which can give the psychiatric personality to this level. So if you are looking for something of this sort, then there is nothing else, and it would be a mistake to do so.
