From a web page on American antique corsets!

'Red wool became fashionable for undergarments at the end of the 1850s and was used for petticoats, cage crinolines and corsets.

The fashion historians, C. Willett and Phillis Cunnington, cite a source from the early 1860's complaining that "the old- fashioned stays are still too generally worn" and "often of red flannel, boned".'
