Ok, I'm taking the plunge. Totally new to premium raw denims here. I fit pretty well in a size(the one found on the label) 29 Diesel. Not too lose, not too tight. I can also fit into size 6 women's levi's(not the premium ones though), and it's quite tight. Problem is, I tried on several jeans today, all were 29s(are these actual wiast sizes? because my true waist is around 30-31) and I could not even get the last button(zip flys are a different story)! All were presumably used(one redline Levi's, and two selvedge brands I forgot) so they should have stretched by now, since this was in Buffalo Exchange(for those not familiar, they are a cool clothing trade-buy-sell shop). Are button flys less forgiving? Should I get a size 27 NS following the rule by on the first page? I just don't know if the sizes posted are actual waist sizes or just those found on the label(I've always thought they were actual waist measurements). I also do not have any stores to try them on. Unless you consider going all the way up to LA from San Diego just to try them on is practical. Or, maybe you can recommend where in SD I can find them? I tried looking in almost every botique in Gaslamp Quarter today and no luck. I did find some G-star raw denim in Urban Outfitters.
