I'm not sure exactly where suede comes from, but I hear leather is just a byproduct of animals being killed for food.
I have 2 suede jackets prior to being a vegetarian, and would this make me a hypocrite to keep wearing them? I don't want to buy a new jacket, but at the same time I don't want to wear slaughtered animal clothing. If suede is safe, then I'll keep wearing it...if not, then I'll look for synthetic leather.
