Wow, I applaud your attitude bro. I would be tore up from the floor up. I dont see how casual wear would do this? I have always been drawn more to equipment jackets vs. Fashion because of the fear of this happening. I hope the best outcome possible for you. Sorry about this experience.
You missed the part where I stood in front of a mirror for a solid few minutes in disbelief, I dont think I've ever had a leather rip on me like that, but as @dudewuttheheck said it may have just been an unlucky combination of a so many factors, my luck just ran out I guess...
