Would someone please tell me where I can find the ジャケット Michael jackson wears while preforming bad during the Yokohama/Osaka performance

I don't think anyone has ever made a remake of that ジャケット so あなた "can get it". If あなた mean that あなた want to buy the jacket, I would rather doubt that あなた will find it on the internet. Therefore, I recommend あなた to look for a normal black leather ジャケット with similar characteristics!
