Halloween Costume Contest!

It's that time of year again!  Ghosts, ghouls, goblins, guys can dress as superheroes and.... girls can be as slutty as they want! (but for only one day... okay, weekend)

I'm going to be honest with you: I am not into Halloween.  Perhaps it's the annual struggle to find decent costumes for my plus size awesomeness; or maybe it's the fact that I can no longer go door to door begging for candy.  Either way, Halloween is a holiday I've always appreciated from a distance-- I'm not into scary movies, candy hurts my teeth, and dressing up is for thin/pretty people.  I LOVE seeing people in costume, I'm just not a fan of doing it myself.

HOWEVER-- this year we've been invited to a Halloween party and I need to get a costume soon before I miss the boat and have to get a psychedelic shirt and claim I'm a "hippie." BOOOOORING!  So I went to "Ye Olde Trusty Google" (that's what I'm calling it now) and found a few not-so-bad options of all different prices. What do you think?? Just remember a few things: I am plus PLUS size, 5'11", live in California, and am a bit shy when it comes to dressing up.  

Let's start off simple: Supergirl. Classic, not slutty, and definitely worthy of my nerdiness.

Marilyn Monroe.  Yes, I have shoes for this, but I would need to buy a wig.

Fairy.  (I secretly love this)

This is, by far, the most complex costume: Vampiress of Versailles (or something like that).

Dragonfly (but I have a feeling I'd be mistaken for a fairy a few times)

Grecian Goddess.  Also would need a wig. I like it but perhaps I should go with something a bit more subtle... like this:

What?

Then I found this HI-larious couples costume:

Opinions are welcome!
