From a series of satirical photos poking fun at the width hoops achieved, probably late 1850's or 1860's.
C.1860 -1862. It was considered a faux pas for the ridges of your hoops to show through your skirt. to fix this, women wore full petticoats, as wide as their outer skirts, to go over the crinoline, to soften the edges of the hoops so they wouldn't show through. They would also add volume to a skirt making it bigger as well. This petticoat is made of cotton, and is decorated with little pintucks and crimped fabric around the hem. It looks like it was made for a young girl of around 10.
