8. Visible Woman Heidi Klum might be a mega babe supermodel, but for Halloween this year, she bared it all. Klum went to a party dressed as a female without any skin. What other supermodel is going have their face airbrushed and come strolling in a blood-splattered gurney? No supermodel. That's why Klum's costume is awesome! [SOURCE]

6. Zombie Iron Man Do we need to spell out? It's Iron Man spliced with a zombie. It's grotesque and awesome at the same time. Compared to the already impressive steampunk Iron Man costume, this one wins hands down. Come on, zombies! [SOURCE]

5. AT-AT Dog For a pet costume, it doesn't get better than Katie Mello's AT-AT costume for her dog Bones. My sister's store-bought duck costume for her terrier is adorable, but it can't crush Rebel scum like this costume can. This is the best dog costume of 2011! [SOURCE]

4. Working Nikon DSLR Camera The best costumes are the ones that do double duty, look badass and are functional. Tyler Card's Nikon D3 DSLR costume sure is dorky, but guess who has the last laugh capturing all those crazy Halloween pics? That's the guy with the dorky camera costume taking pics of everybody in their dork costumes. Say cheese! [SOURCE]

3. Princess Vader You've never seen Darth Vader like this before. Completely emasculating him by pinking out his mask and cape just deserves all sorts of praise. The only thing better would be if underneath it all was a Princess Leia! Man, that's twisted. [SOURCE]

2. Gaping Hole With Two iPad 2s Wanna look like somebody took a shotgun right to your chest? Grab two iPad 2s, duct tape them to your chest and just fire up FaceTime chat. Don't forget to deck it all off with fake blood. That's crucial to making it convincing. Best costume use for an iPad 2? You betcha! [SOURCE]

1. Twin Top Gun Babies in F-14 Baby Carriage It was a tough call, but this year's best costume belongs to a pair of eight-month-old twins and their dad. Babies dressed as Top Gun's Maverick and Goose? And their baby carriage is an F-14 jet? And their dad dressed up as a runway guide? It's adorable. It's cool. It's a family package. BEST. COSTUME. EVER. [SOURCE]

9. Nyan Cat I don't really care whether or not you think the Nyan Cat song is annoying or not. The fact that anybody went as an Internet meme is crazy enough to win it a spot in our best costumes of 2011 ever. Who cares if it's all cardboard? It's the Nyan Cat, now get nyaning because 44,895,222 views is not enough. Let's boost that to 50 million views! [SOURCE]

10. Rocketeer Rocket Pack One word: recycled. That's right, this Rocketeer rocket pack isn't just a faithful reproduction, it's made out of trash and is super cheap to make. Two soda bottles, two shampoo bottles, a few cereal cardboard boxes, and paint and bam! Instant rocket pack! [SOURCE]

7. Pixelated Metroid Forget about going as a sexy Zero Suit Samus because the only way to do any Nintendo costume is to go old-school — as in pixelated 8-bit old-school. Take that new school! [SOURCE]

8. Visible Woman It's crazy, isn't it?
