Halloween is so close and no costume ideas yet...

I will be working on Halloween this year, and I will be dressing up...I do every year anyway...I do love Halloween...however I have no idea what so ever I should be...

I did at one point go to a school dance in a green thing similar to the one above, with my face and hands pained green and antenna in my hair...I was an alien of coarse, albeit with out the Louboutin heels...and in the 8th grade with an amazing amount of courage when I think back on it...I'll need to be a bit more conservative this year...any ideas?
