I would contact Southwick and ask who their retail partners are in your area. They definitely offer MTM and a reasonable price. Their Douglas pattern remains a standard option.
Thank you for introducing us to "Cargo Cults". In skimming the linked article it occurred to me that the affected cultures were both technologically and intellectually challenged. Not in the sense of cognitive impairment, but in the scope of their education. In many ways the affected cultures were very little advanced from the late middle ages. Then conquerors swoop in from the sky (literally) and bedazzle natives with inconceivable advances in materials and technology. Unfortunately, the natives lacked the educational scope to understand the sudden experience- it was completely alien to them. Thus the newcomers were viewed as deities and the natives later paid homage to attempt to regain the favor of deities.Snip
I can't help drawing a comparison to the idea of cargo cults discussed by cultural anthropologists and ethnographers (another full disclosure: I used to be married to one). Cargo cults (mainly post-WW II) refer to the great admiration and enthusiasm, seen first among Melanesians and Pacific Islanders, for objects that were part of Western society. These objects were introduced by European colonizers, often through airdrops, when they invaded or acquired many of these nations and islands. Colonialism depends on the extraction of raw materials and wealth from the subject nations and also creating markets in those nations for the sale of finished products to further enrich the colonizer. Cargo cults are an almost bizarre outgrowth of this process. Briefly, a cargo cult is a system of beliefs and rituals among indigenous peoples that they trust will induce a more advanced society with technological prowess to deliver desirable goods to them. You can read more about this in the link at the end of this post.
My point here is that Japanese behavior toward Western clothing has an intriguing parallel in cargo cults, although in a more modern way. There are major differences: Japanese society is technologically advanced, and quite the equal of Western societies in skill and craftsmanship in clothing, although this was not the case a few decades ago. But their adulation of Ivy Style and their attempts to recreate and reinvigorate a fashion that they feared was becoming an anachronism or even moribund, does appear to resemble the worshipful attitudes of the nations that formed the old cargo cults. In the fine attention to detailed work in many articles of clothing made in Japan, I see some of the old rituals associated with cargo cults. And this is all the more significant because traditional Japanese style in clothing -- kimonos, haoris, getas, etc. -- has literally nothing to do with western dress!
