Ruined is a very strong word but somehow this "new Denime" made me less interested in the recent releases.
When Warehouse took over I was very excited. Knowing they wanted to go back to the origin and rumors have it that Hayashi-san helped them (inofficially of course).
The "new" XX denim they made for the 220 faded extreme quickly. Allegedly this is how the first run(s) of XX denim faded. I don't know. The XX denim I have on my pairs is of course from later runs and this faded rather slow. The fit of the 220 is very different to the original XX model (but after all I liked the fit, so I won't complain too much).
All in all, these releases feel very Warehouse-like but with a different patch, red tab and hardware. Original Denime felt more rugged/unrefined. Even the 220 model now with different denims, changes of cut is totally Warehouse-style.
In that regard, the 30th Original Line was a very good product and got the sense of "old Denime" very well (just don't talk about the 3-6 years under Wego before they introduced the original Line, they watered down Denime).
