circa 1853 Found from another board with that date. All research states 1856 when the crinoline came into fashion. If anyone does find primary sources stating other wise and cite them I would be most appreciative.. Until then I will go with what "English Women's Clothing in the 19th Century","Costume in Detail", "History of Costume", "Godey's Ladys Book" all state.

Crinoline: undergarment, the hoop for the hoop skirt. Made of either whalebone or steel, hoops were sewn onto tapes or into a fabric skirt to make a hoop skirt. Shapes varied based on fashionable silhouette.
