never saw this thread before but here's my take on the subject.
Got 30+ jeans and got APC, Levi's (regular 501's, stf's, Capital E, LVC), Nudie, Hugo, Hugo Boss, Ralph Lauren, Evisu, Diesel, Edwin, Blue Blood, Fake London, Latjo Lajban, Replay & El Charro.
Fav depends on the mood and what I'm doing and where I am.
Lately I don't wear a lot of denim but when I do it's probably one of my El Charro's, APC's or modded 501's.
