It's a fairly heavily tweaked Truly Victorian 432, the tea gown. Really cut down on the fitting I had to do, though...great patterns! I'd recommend any of 'em.

I've actually never bought steel corset bones in my life! Probably because I haven't done anything c1875-1900 up til now, so I've found cable ties perfectly sufficient. Will end up buying at least some spiral steels if I make any more natural form, though, because those ties just don't bend like I need them to. And hey, whatever boning works for you! :D
