There is a so called hierarchy when comparing superiority and quality of current denims. The highest ranks includes those like current Japanese super denim like momotaro, eternal, samurai, the flat head, pure blue japan, denime, studio d'artisan, fullcount, somet, sugar cane, etc. These denim are expensive and i mean  can be super expensive not becoz of the brand, but purely for it's craftsmanship and nice cuts. Some of these brands might be unheard of but for denim enthusiast they are much more known compared to brands such as true religion etc. Call these Japanese denim as the Aston Martin, or the Bentley, or the Ferrari of denim.

Then there are Nudie, APC, Naked & Famous, Imperial, Edwin SEN Japan, etc which would be in the second ranking of denim hierarchy. These are good quality denim superior to other denims in the market as we know it today but not as good as the japanese ones i have just mentioned earlier. These brands, especially Nudie and APC are famous and picking up in popularity is due to it being worn by celebrities. These denim brand can be categorized as the Audi or the Mercedes of denim.

Then you have the other brands like Topman, Gap, Unqlo, etc etc. These jeans has a decent quality to it and also has a decent price. The price is parallel to it's quality.

Then comes lowest of all ranks of denim. These includes True Religion, 7 for all mankind, diesel, Ed Hardy, and other designer brand denims. These denims are, should i say, hideous in design and cuts, for example, Ed Hardy. In this denim category the quality and cut and craftsmanship are poor and hideous. But that is not the reason why it is being categorized so low. The reason being, is, that the price of these denims are ridiculously expensive with the kind of quality they offer. I.E the quality doesn't go with the price. They are as expensive as the superior Japanese denim but the craftsmanship arent comparable at all. So these brands tries to rip consumers off. These are expensive becoz of its brand, not quality, unlike the Japanese premium denim.

Then comes the odd one, the Dior Homme 19cm and 21 cm denim. This odd onei shall put it somewhere in between the 1st and the 2nd rank of the hierarchy. This is so becoz the quality and the build of the denim is as good as and on par as Nudie, APC and such or even much more and somewhat, slightly below the Japanese denim brands. But the price of Dior Homme Raw Denim is as expensive as those Japanese denim. But i find this as ok coz you are paying for its quality and also brand in the same time.

Finally got my first raw jeans, N&F skinnyguy Indigo Power-Stretch with Grey fill. I didn't do much research so not sure whether it is a nice pair of raw jeans not. bought it because the color suit me, nice cutting and reasonable price.

have a question here, I think it is non selvage, means I can alter to perfect length??it's very long and I dislike to roll up.
