I'm going with either French maid or flight attendant. I'll decide once I figure out what I'm actually doing on Halloween. By the way, if you're looking for some inspiration, my list Halloween Costume Idea -- Girl Edition might be right up your alley ;)
I wish we could go out this year to a club party but can't - but if I was, I would be a sexy gothic witch; the black eyeliner, nails and lips, long black wig, super tight fitting black dress with the side slit up to there and bodice cut down to there -- but damn it, I gotta stay home this year!! I can fantasize though, right?
I don't know why I didn't see this question before, but I'll give a post-Halloween update. I dressed up as Mad-Eye Moody from the Harry Potter book/film series. On Saturday, I went to a local ArtsFest with my wife and kids and they had a blast. I also saw a young lady (probably around sixteen) there dressed up as Hermione. When I saw her, I said, "Hello, Ms. Granger." It took a second to register with her, but she smiled and replied, "Hey Professor Moody!"
On Sunday, we went to check out Sesame Street Live's "1-2-3 Imagine!" show and then hit a few trunk-or-treat parties at some of the local churches. Unfortunately, it is much safer to take the kids to these types of events around here instead of going door-to-door like I used to do when I was young. A few neighborhoods throw block parties, but living out in the boonies like I do makes it a bit harder to go to one of those.
