I also have been collecting lots of pictures of extant petticoats in museums and private collections, and in so doing I've come to a realization; nowhere can I find an example of one with a ruffle on the bottom. Hmm.
|Hooded caraco and quilted petticoat, 1775|
|Mid-century quilted petticoat|
So I think I'll be leaving the pink ruffle off of my petticoat, and save it for an upper petticoat or trim on something else. I'll also be using the thinner fabric and an applied waistband to close. If anyone has seen illustrations or garments contrary to my research, I'd love to know about it.
