Spock

Well to be more specific… baby Spock. This Spock costume will transform you little one into a “logically” the most adorable Spock ever. Find it at customercraze.com.

Up next is everyone’s favorite wizard, Harry Potter. For one night a year you can become a student of Hogwarts School of Witchcraft and Wizardry and maybe cast a spell or two.

Harry Potter

No matter your age, what geek wouldn’t want to be the chosen one – Harry Potter this Halloween? He’s got it all, good looks, brains, a gift at fighting against the dark arts and mad Quidditch skills. So don your robe and have fun “trick” or treating.  Here’s a costume at buyharrypottercostumes.com.

Hogwarts Student

It’s probably safe to say that a Muggle never looked so good. One thing’s for sure… I bet this costume would leave Ron Weasley speechless, not to mention the nerd in your life. You can find it at buyharrypottercostumes.com.

Hedwig

Mom and dad can dress their child up as Harry Potter’s favorite owl, Hedwig, and without a doubt be a hit this Halloween.  There’s nothing cuter than a baby Hedwig. This costume can be found at buyharrypottercostumes.com.

These next four costumes are perfect for any nerd. From Battlestar Galactica to a classic nerd costume, everyone can release their inner geekness.

Master Chief

You’ll have the power necessary to combat the threats posed by the Covenant, and to defend against the Flood in this truly awesome Master Chief costume (this particular costume is Halo 3 Master Chief Supreme Edition). But if this costume is too pricy for you, and at just under $700 it is a bit steep, you can do a quick search and find lots of great Master Chief costumes more reasonably priced. This one can be found at meijer.com.

Starbuck

This is my favorite costume. Being a big BSG fan and Starbuck being my favorite character, this would be my first choice for a Halloween costume this year. I think I’ll be frakking cool in it. Now, I need to find me a short-haired blond wig. This costume can be found at costumecraze.com.

The Classic Nerd

Ah, the stereotypical nerd costume. It’s the image that is conjured up when we hear the word “nerd” or “geek”, although, nowadays, we know that nerds and geeks can and are quite sexy. For the laughs though, you can wear this classic Nerd costume and maybe solve some mathematical dilemma and impress all the ladies this Halloween. This costume can be found at brandsonsale.com.

The Sexy Nerd Girl

Who says nerds can’t be sexy? In fact, being a nerd almost (notice I said almost) always means sexy in my book. And this costume will most definitely have ALL the guys drooling.  This sexy nerd costume can be found at yandy.com.

As you can see, there are many great nerd and geek Halloween costumes to choose from. All of these costumes can be found by doing a search online, so you can find the best deals for you. And these costumes are sure to be popular for many Halloweens to come.

Happy Halloween!
