If that probably helps: There´s two kinds of "brut" denim jeans this S/S 2006, one being made in Japan, one in Italy. The Japanese is nicer quality and doesn´t stretch out as much as the Italian production, I personally found the colour a bit more appealing as well (a bit more indigo rather than just dark blue). Both should cost about the same in shop, so if anybody is undecided, just have a look at the inside of the jeans. In terms of quality, it´s getting a little tired hearing stories about deterioration of quality again and again, I´ve got a similar pair of raw denims from S/S 2003 and they are absolutely the same quality, albeit the price had been a lot higher back then.
Believe it or not, sometimes, when the quantities are high enough they happen to drop the prices as well at a maison like Dior. Please keep in mind that the quantities are by far higher in these seasons than they were back at the start, also, those jeans are rather easy to produce on a bigger scale than, say, those ripped and coated ones from S/S 2004.
