Wonder if in the olden days, like flying private jets, the moral position on wearing fancy clothes were mostly held by those who cannot afford them.

In the case of things like Elizabethan sumptuary laws ( https://www.bl.uk/collection-items/proclamation-against-exce... ), it was definitely an old money vs new money thing. Conspicuous consumption was disruptive to the social order, and tended to force an "arms race" of spending which led to a sort of "precarious upper class" situation who could afford it only by going into debt.

Does anyone have a well sourced "origin story" for why mixed clothes might have been prohibited in Judaism?
