This oversight might be due to the fact that the show was filmed in Tucson, Arizona, during the summer months.
A fashion slip
In some episodes, you can catch a glimpse of Caroline’s bra when she moves just the right way. Considering the series is set in the 1870s and 1880s, this is a bit of an anachronism — since bras weren’t even invented until 1912!
Some of the women also sport hairstyles with perms or curls on set – a look more at home in the 1970s than in the 1880s.
On a similar note, you might have noticed that most of the men in the series are clean-shaven, which is a far cry from the historical photos of the era. In reality, the vast majority of adult men sported facial hair — beards were all the rage. In fact, Charles Ingalls himself had a beard for most of his adult life. It seems like the show’s grooming choices didn’t quite match the rugged fashion of the time.
