If you're more "Meh, who can be bothered?" than "Awesome! Candy me up!" then the best possible costume solution is the DIY Minecraft Creeper head. It's basically a box with some paint on it. Easy. Lazy, even.
If you have nothing on today, then consider making a Reshiram. You don't know what they are? Watch the video and wonder where some people get their spare time from.
Are you handy with the eyeliner? And you're a cute girl? Then manga is a great option. Just lay on the MAC colours nice and thick, then throw on a colourful wig. Easy. Now all you need to is to throw some cute manga girl poses and you're set.
If these don't grab you, consider strapping on a couple of huge plasma TVs and voila, you're an instant iPhone.
Happy trick or treating.
Cheap, easy and fun.
A whole lot of work went into this costume. Would take more than one day to turn around, so one to think about for next year.
One of the easier manga costumes for Halloween - just fi your eye make-up and throw on an aqua wig!
This guys describes it as "just awesome to wear around". So feel free to try it out on the tube tonight.
This is very cute. All you need for a DIY Link costume is a couple of T-shirt, some belts and a sword. You have one of those, right?
Reko Rivera and John Savio used a couple of 42" displays to make these life-sized iPhone costumes. Definitely ask your mum first before you make this.
