Addendum: A Tutorial: Sense and Sensbility Bodiced Petticoat
While I am still waiting to get pictures of the completed bodiced petticoat, here is an extant example of one of these garments from Boston's Museum of Fine Arts (MFA).
It's of a later date than the 1790s, but is a lovely object nonetheless.
The MFA refers to it as an underdress. There may be truly a difference between an underdress and a bodiced petticoat, or terminology used then and now differs, or synonyms are floating around. I cannot judge.
Anyhow, the museum explains that the garment dates to the early 19th century (the labeling that came with it said 1820-1825), and was worn by one Mehetable Stoddart Sumner (Welles). It comes from the Boston area.
It's made of plain-weave cotton, with cotton embroidery, and features the use of twill tape in addition to the cotton.
It has drawstrings at neck and waist, and back tie closure...whether that is separate from the drawstrings the text does not make clear.
Want to see it in detail? Visit the object, accession number 49.876.. If the link doesn't work, the garment's accession number is 49.876.
Lest you believe that all bodiced petticoats were complex, here's a dramatically simpler one, with twill tape for shoulder straps. Not something to show under a sheer dress, I would think?
