2) getting the most perfect fitting jeans possible due to stretching (this may be more a property of the selvedge than the fact it's raw, however)
there's nothing wrong with gettin some endo from your local college dealer at a reduced price. it'll still get ya high.
but there is nothing like gettin a good sativa from the club; it'll get ya really high. And in the long run, it'll last longer because you'll need less to accomplish the same thing.
I wear raw because it's fun to have things develop and the quality is sweet. I also like natural looking fades, and not just the usual high contrast. I have some edwin slim bucklebacks that I'm going to wash out.
