. . . well, almost.
I have Castiel's petticoat done minus hook and bar closure, and Gabriel's bustle/petticoat combination is finished minus hemming and buttons. Cas' will be done as soon as I can convince her to put on her corset and bustle for fitting. It may need to be shortened, but if so I'll add tucks. Here's what hers looks like:
Gabriel's bustled petticoat is based off of some images I found online. I won't be able to continue work on her outfit until she returns from her fieldwork next month.
