Halloween is one of the greatest pseudo-holidays of the year for a wide variety of reasons. One of the biggest being: It's the one night when women everywhere drop their inhibitions, and act and dress in ways they would never even dream of the other 364 days. Party gold.

And while you're sitting at home wondering what to wear, everyone is going to give you advice on the perfect costume that'll get you laid. (The absolute best advice though, you'll find here on our friend Bobby Rio's site, TSBMag.com. Pure. Fucking. Genius.)

But if you're looking to make a connection with a like-costumed lady, as this Captain Morgan commercial from a couple of years ago illustrates, then knowing the odds of what she'll be wearing is key.

So I asked the experts over at Spirit Halloween, the largest Halloween retailer in the world. I figure if they know what the most popular costumes are this year, you've got a shot at running into one.

Here are 5 of their top sellers for this year (pictured above left to right):

Princess Leia:
Chalk the rejuvenated popularity of this one up to Olivia Munn's repeated wearings. So sexy Leia from Return of the Jedi may be showing up at a party near you. You can go Luke Skywalker, but being that they are brother and sister, your chances are slim. Go Han Solo, and go for the rescue.

Lt. Uhura:
Star Trek: The Movie was a blockbuster, so expect the "Trekkie nerd" stigma to be gone this Halloween. Especially when she gets to wear a super-mini uniform like this one. A colored t-shirt, a cutout Federation emblem, a pair of black pants, and you can go where (hopefully) not to many men have gone before.

Robin:
I always knew Robin was far too feminine to be a guy. Find one of these at your party and you can go the obvious Batman, but I'd go Joker and ask her if she likes magic tricks. Then go make something disappear.

Sexy Kitty:
Something about Halloween brings out the sexy kitty in many women. At the parties I've been to, besides cops, cat costumes are everywhere. And whether they'll admit it or not, they always fall for dogs.

Kate Plus 8:
Yeah, her 15 minutes aren't up yet. And with that hairdo firmly entrenched in pop culture, expect to see these wigs popping up everywhere. Dressing as John is easy: baggy jeans, slicked back hair, and a d-bag Ed Hardy T. But since the hate is flying, you may want to consider going as a bodyguard... or a 9th Kid Looking For a Mommy.
