Would someone please tell me where I can find the 재킷, 자 켓 Michael jackson wears while preforming bad during the Yokohama/Osaka performance

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