I'm planning to pick up some "good" jeans in Japan, and I am a little unclear on something. If a pair of jeans is unwashed, is it expected to shrink considerably upon washing? If I buy a pair that fit properly when new and then wash them (I will wash them, I'm not as committed as some of you) will they shrink a lot? Is "raw" and "unwashed" denim the same thing? Assuming I pick up a pair that has no tell-tale puckering at the seams to indicate that it's been washed, should I assume they will shrink? Am I making any sense at all? thanks.
