Oh I wish I could do a Halloween party but Im away for the very day

Well I was going to go as ''Alexander'' from ''A clock work orange'' (I had the hat and EVERYTHING!!! :D) For that you need a black hat, large fake eyelash to go on bottom of eye, and lots of mascara to make your fake eyelash look extra long when you draw massive pointy spikes under your eye!! If this sounds confusing just look at the cover ;) That film is very good :D
You could always go for the whole ''evil fairy tale character'' vibe :D Alice from Alice and wonderland is a fun one to do as you can do everything really crazy!
There is also the whole ''zombie'' idea but i always think thats a bit boring and for people who cant think of anything better to do :D.
Go for something different and un traditional (always funner :D) Plus Halloween is a night where everythings CRAZY!!! (funest night of the year I think :D) Hope you have a great time and let me know what you decide!!! Look for inspiration from horror films :D
