Found this on line on The Independent. UK Newspaper. Micheal Kaplan talking about his favourite costume Jobs. Fight Club was Number 2. I'm gonna go out on a limb here and say he is talking about X-Marts jacket
He's very easy going, very laid-back, he's fun, he's funny, loves clothes, loves to collaborate and he doesn't just want to wear anything. He is clear who the character is and that is important to me and we have a great professional relationship. In Fight Club, his character had no money, he was living in a house that didn't belong to him and his clothes couldn't be fancy. I decided he was going to be a person who gets great things in thrift shops, because I do that and I know they can be found. The problem was that we needed multiples – I couldn't just go to a thrift store and buy him a great leather jacket because of the fighting scenes and stunt doubles. We needed maybe 12 of the jackets. I made his clothes and found this old, hard leather base they used to make jackets out of in the 1970s – it's almost like car upholstery, not like the soft, buttery leather they use now. I had it dyed and I wanted it to be the colour of dried blood. We designed it and fashioned it after the way clothes were made then but it looked like it was from a thrift shop – we broke some buttons, tore the lining and put stains on it to make it look like something somebody wouldn't want anymore.
