Definitely a great topic. As a youth I believe I always wore Levis. Eventually I came out of my 501 existence, and looking back.... well it is hard to understand why I was so bitten by the Levis style. It was the times I guess. I had only one pair of old Diesels that was tight fitting and faded. Somewhat daring I suppose compared to my usual style. I never forgot how much I liked them.
For a period after that I wore We are Replay, G-Star and also Pepe jeans. One day I remember I discovered a cool pair of vikers in an Amsterdam shop. It was a turning point. From then on I started to wear Diesel jeans almost daily, mostly wearing viker, safado, larkee, even zatiny, distressed or plain. Later I started buying darrons, and I still like that cut. My absolute favorite wash was 8B9. I had it in viker and safado, now in thavar.
It was only when I recently discovered this forum that I moved to slimmer cuts, and now I have migrated to thanaz, thavar and shioner. A couple of tepphars too. I have a mix of plain and distressed washes. Only rarely do I wear jeans in the office, but when I do I go for rather plain washes. The distressed ones I rock on my spare time. Having become a virtual diesel addict, I have of course added too many pairs lately, so I need to slow down. Got a pair of Tepphar 804K today though :) - last one for a while!
