Punkgirl's Last Halloween?

Punkgirl decided last week that she was no longer interested in trick-or-treating, after her pet rat (who she had planned to take along on her shoulder) passed away unexpectedly.  I had forgotten her plan to take him along, and her announcement that she was not celebrating Halloween not only took me by surprise but saddened me greatly.

Halloween is my favorite time of year, slightly eeking out Christmas (and only because Christmas candy is generally a bunch of stuff I can't eat.)  I love having the chance to dress up, to be someone else, and to watch my family enjoy the same.  Punkgirl is 12, and pretty soon she'll hit that age where she won't want to dress up, just because--so not wanting to go this year because of the rat is bringing that home a little too early for me.

At 41, I'm realizing that my pre-teen is heading towards "teen" faster than I can say "tween."  I'm left feeling like she will no longer have time for costumes and nerdiness, which is why I've tried to cram them all in this year, with Comic Con and King Richard's Faire.  I'm working on fitting in a SuperMegaFest too, just to give her one more silly activity before her 13th birthday.  She already knows about Santa, and the Tooth Fairy, and the Easter Bunny, so the days of forcing Coffeeguy to dress up so I can "catch" Santa leaving the presents won't come around again until Rose turns 3 or so.

That was why I was so thrilled on Saturday, when she came home after dance class to tell me that all dancers could wear costumes to class next week (which was reserved for the kinder-combo kids in previous years.) She pulled out an old black jazz costume, a plain black Lycra jumpsuit, and a new mask she had bought for her wall.  She couldn't decide what she would be...Goddess of Death? She added a pair of rainbow wings.  Goddess of Rainbows? I suggested covering the wings with black fabric and getting some black feathers and a tutu--a stylized Black Swan kind of costume.  She hasn't decided yet, but I'm so glad she's trying to figure out what to make.  My baby will have at least one last year of childhood before she's "too old" for trick-or-treating and Halloween.

These are the pieces we have so far:  

Any suggestions from other suck-at-home moms out there? (Or if you're not sucky at home, even better...give a girl a creative tip!) I don't have a lot of disposable cash...but I want this to be a great costume, since it might be the last!
