There was no historical interest or goal to develop a sun-burn, much less a sun tan. Men customarily wore hats... even when they had to weave them themselves from palmetto (which was evidently not uncommon). Wearing a dilapidated hat was evidently considered less odd than wearing no hat at all...
"The cracker is independent in his ideas of dress or costume. A felt hat of a nondescript color, but once probably white...completes the costume..." (Lippincott's Magazine, 1870).
Most Southern country women didn't bother about hats, but wore "cracker bonnets" generally with "curtains."
It was frequently observed among country southerners that their garments were constrained in length, rarely reaching their ankles... evidently a result of the width of their customary homespun goods. Both the men's trousers and women's "cracker gowns", making ankles frequently obvious...
Crackers near the Georgia-Florida borderlands... (1858):

1860s illustrations of contrabands etc. in the South occasionally show the trousers rolled up above the ankles...
Common women's skirts were evidently often rather shorter than the fashion too... From about Vicksburg, from a Union soldier:
Again from the Georgia piney woods...
Syrgley's "Seventy Years in Dixie" (1891), based on his own recollections and the statements of T.W. Caskey, laments that the plain common dress of the mid-19th Century Southerners was so ill considered as to have been practically undocumented outside of the observations of swells, in favor of the portraiture of folks with money...
