on the topic of cloth and geography, please note that many users do travel extensively and thus don't necessarily use the garment in the place they live. For instance, as we were here recently talking about thick overcoats in HK, I can well imagine that said gentleman, indulging in bespoke wear, will be for instance in cold Tokyo for some fine fattier sushi during winter. Another example would be a mainland Chinese living in Singapore who returns home often for a taste of the cold weather. To conclude and to show it is not only an Asian matter, I imagine a very high number of SF users are US based but travel either for work and/or holidays to Europe, where it is much colder than, ex. in Texas.
