Too damn hot to wear a long robe! They got villainous bikinis, maybe?.
I'm sure they do, and if they don't, create one. What's the fun of being a villian if you can't create your own fashion trend. Skull or bat motif perhaps.

@GeorgeRocheleau I have 2 drawers full of costumes I made...will get right on that the next rainy day!
