Forget stretch jeans. Â They look sort of wierd on a guy. Â Excepting the stretch, the APC standard would probably fit your bill. Â Check them out at Stel's and tell them that Fok sent you. The old standard (if you can find them somewhere) have a higher rise, and are closer to the 501s. Â Thye are also reasonably priced. Â Helmut Lang also does a classic, straightleg fit (get the bootcut though, it is really a straightleg. Â The classic cut is rather tapered.)
Maybe some cuts/fits are a dead giveaway, but I'd honestly like to see someone point out 2% Lycra in combed cotton denim with 100% accuracy. I don't think it can be done. As I understand it, FTC regulations require any fiber content OVER 2% to be listed (i.e., apparel with cashmere content under 2% cannot be called cashmere fabric). Lycra is the one exception, because its performance abililties at just 2% are significant enough to warrant its inclusion in hang tags and labels. But stretch jeans looking weird on guys? Depends on the style, I'd say; not on the lycra itself.
