I bought a pair of these: Pure Blue Japan Vintage Chinos http://www.purebluejapan.jp/archives/528
about 6 months ago. They are nice and slim but the material has faded rather quickly similarly to the way jeans fade. The upper thighs and knees lost the most colour along with the seams. I didn't follow the hand wash only instructions, but thought that was ridiculous for a pair of chinos. They are low rise. The waist sizing seems to be looser than on their jeans. The material has deliberately uneven weave. Oudside and inside side seams are double stitched, similar to newer style jeans.
