Aw shit, son.
ALICIA'S HALLOWEEN COSTUME, THAT'S WHAT.
VOILA!! And lo, I am successful. If you're comparing, I'm the first to say that there are some obvious inconsistencies with the reference material, but they all have a purpose. The length was shortened for mobility and drive-in-it-ability. The neckline was altered because a high neckline makes Alicia's expansive boobs look like she's smuggling a bowl on her torso. The shoes are flats (painted, they were originally purple) because she'll be wearing this all night and wanted to be comfortable. The gloves are shortened because she didn't want to be pulling them up all night long either.
The wig started out stick-straight, and other than suffering from a slight lack of fiber density, I think it turned out well, and still moves rather than being rock-hard and immobile. The crown is also attached to the wig itself, so no pesky headbands to worry about. Keep in mind that wig heads are HELL of smaller than real heads (and especially smaller than hers, since she, like I, suffers from an abnormally large cranium) so the flips sit higher on her head and the crown looks a little less ridiculously tall and tiny.
Any criticism is welcome, though likely won't actually be fixed since this is just a Halloween costume and she's certainly happy with it as is.
All in all, a fun experience. Except, that is, for the SIX YARDS OF RUFFLE IS HAD TO HAND GATHER AND HEM. Uuugh.
