the gf and I are thinking of having a halloween party at my apartment! I'm excited.

We're thinking of going as fred and wilma flintstone.

Other costume ideas(some may not work as gender neutral costumes):

1) reverse cowgirl - I saw this one last year, just get cowgirl glothes(bandana, blue jeans or denim skirt) and put 'em on backwards.. It took me a while to figure out what the hell the costume was but it's pretty funny when people get it

2) the smurfs, any smurf, if you can get a group of people to do it it's even better. Any costume that requires painting large portions of your body is always a good costume

3) captain planet. see previous comment about body paint.

4) zombie. The zombie is a classic halloween costume, and if done right is very impressive. Plus, fake blood is fun.

5) pig chef. get a pig mask(there are some really creepy ones you can find online), and drop by any uniform store or cooking store where you can get white chef clothes, with apron and hat. Add some fake blood and accessories as you wish(cleaver, fake human limb, frying pan, lots of room for ideas). This is one of my personal favorites, very creepy, and works for an EXCELLENT costume for anyone participating in a haunted house. Nothing says scary like an angry, squealing, cleaver wielding pig that wants to cook YOU for dinner.

6) Planet of the Apes. I'm SURE you can find cheesy masks like the old movie online. Add a wild-looking "human-slave" on a leash or chain with shackles and you're set. Pretty good group costume.

I've been to parties with halloween costume contests, and the best ones are the ones that have a little "skit" to go with the costume. If you're trying to find a rockin' group costume that will dominate any such contest, this should win big:

Do "Thriller"! Do the typical zombie costume, have someone be zombie michael jackson, and learn the dance! I tried to put this together my senior year at college but it fell apart for various reasons.
