When I first read the lines with josie-josey I wondered if it was a sack-like coverall dress. Then I found the garment called a joseph (a cloak) defined in the dictionary. Thinking of minstrel get-ups , including the long blue coat, I thought it likely.
The 1849 song posted by Richie says "wa'nt her bustle heavy." Does this refer to a "big bottom" or to the undergarment pad addition? The word bustle for the big pad was in print by the 1790s and the bustle was used off and on through much of the 19th century. Who has a fashion history?
Farther on in the same song, she has a josey on. Could it be another name for a bustle? Seems it is either that, or a garment which covers the gal. For slaves, often only one layer was both outer and under garment. Was this called a josey? (Or is it just a nonsense word?).
That's a problem with these words; meanings change with time, or they become nonsense. Very difficult to pin down.
