pleather is good for capes and cloaks. Spandex is good for muscle shirts, you can also use vinyl, cotton, fleece or even fiberglass!
That all depends on who is making them, and what the character wears. However, I always recommend making cosplay outfits out of materials that you would use for every day clothes. Avoid using materials like overly shiny and cheap costume satin. If you make your cosplay as you would if you were to wear it every day, it will end up looking more realistic, and less costumy.
It is basically an interview that describes your cosplay. they have questions that you answer such as , What got you into cosplay? How did you decide on this cosplay? How did you put together this cosplay? Basically a self interview on cosplay.
