I don’t really do much denim outside of IH and I have, or have had, most of them. Never have I bought a new IH denim and thought «oh shit, these are too similar to that other IH denim». But Haraki-san is not a fan of slub, and likes an even hand, so there often some similarities. Otherwise weight, hand, fading, pattern etc are all pleasingly different from denim to denim.
