See, Tyler Durden is anti--consumerisms, so the stuff he wears is most probably second hand. The red vintage leather most definitely, and the patterned tank tops and tees you should be able to find at a second-hand store or some vintage clothing store. Just think methodolgy first, then be creative.
For Versace, the most over-priced shit ever made, to come out with something like that is just fucking pathetic, when 2nd hand is definitely the way to go.
