I used Truly Victorian patterns for all three components - bustle petticoat, skirt and jacket. I did a post a while back when I had finished the petticoat and skirt - it is here if you're interested! http://www.craftster.org/forum/index.php?topic=352905.0
I ended up with a different corset as foundation, a demibust for the better fit with the period shaped jacket.
TV101 bustle petticoat
TV216 1875 Parisian Trained skirt (as pattern except I added detail on the side panels)
TV405 1972 Vest Basque (modified to lower neckline, changed collar, omitted cuffs, pointed center front)
Please to be ignoring the derp poses!
Just FYI, this is the makeup tutorial I used: http://www.youtube.com/watch?v=04V8qyMtrrM&feature=related
