You're witnessing a few things, I think:

- the culture of modesty affected both men's and women's dress and grooming habits, women somewhat more, but men also quite significantly

- stylistic haircuts were not available in rural settings without professional barbers/hairdressers

- clothes were not as stretchy; cotton and wool were coarser, nylon more rigid, polyester and spandex nonexistent

- the economics of the time favored thicker, more durable fabrics over thin, friable, wears-a-hole-after-one-year fast fashion fluff

- sun exposure, particularly among white people in the United States (which is much sunnier than Europe), was rarely avoided or mitigated, particularly among the working class

- childhood nutrition was worse, particularly among the lower classes in the period between the first wave of enclosure/monoculture/industrialization of agriculture and the dawn of nutrition science (hence fortification)

- these are images that the government did not want to show people, of course there's a higher prevalence of unattractive people!
