Logic or no logic, the fact remains that it was easier to develop special and general relativity than to imagine trousers secured with leather belts inserted into belt loops. That does not, however, mean that pre-20th century pants have been dropping off. Trousers were highly cut and waist-fitted to the contours of their wearers, as such tailoring adjustments cost pennies. Then, in the 1820s suspenders have been invented. From then onwards, even mass manufactured trousers could be worn without individual fitting (though tailors’ services still cost pennies).
These trousers were cut very high, which made belts impractical. No one made pants with loops or used belts to tie their trousers. Pants with belt loops could have been made in prehistoric times. Yet they were not. The 19th century cowboys could have displayed those huge brass buckles on their wide leather belts that one sees in the Hollywood movies. They did not. These movies are as faithful to history as the ones showing pre-historic men in hippie outfits and leather boots. Still "everyone knows that cowboys wore humongous brass buckles on their belts." There is a whole industry of authentic cowboy belts and buckles. Wearing such accessories seems to be a logical thing for a cowboy to do. The real cowboys did not know about that and wore suspenders.
P.S. Я уже упоминал как-то раньше - если вы читаете по-английски и не читаете shkrobius'а, то многое упускаете. Он один из самых интересных дневников в моей ленте, и это при том, что я довольно часто с ним категорически не согласен и несколько раз спорил на повышенных тонах. Когда-то, когда у меня будет много свободного времени (ха-ха), я перечитаю весь дневник shkrobius'а с самого начала. Более интересные и душеполезные занятия есть, но мало.
