So where will Zac Efron and Vanessa Hudgens be on Halloween night and what will they be dressed like? While that is yet to be determined it appears that one of the favorite Halloween costume couples for this season for tweens (and older) will be the couple that are now universally known as Zanessa. So how do you dress up like Troy and Gabriella?

Zac Efron & Vanessa Hudgens on Halloween? (Wenn)

To keep from getting arrested the first move to make is not to pull of a stripped down Vanessa Hudgens bare photo outfit for a costume. But all kidding aside you can really pick any of the looks from Zac and Vanessa as Troy and Gabriella from High School Musical.

Or if you want to go as Zac and Vanessa in real life you'll need to pull off the hair. Zac's patented look for his locks is only going to work on a few guys with blue eyes so if that's not you - don't even try it. And a warning, don't try that weird "Pebbles" (you know from the Flintstones) look that Zac had the other day. Details of that look are here in this article.

If you have thick hair like Vanessa you can basically let it flow down your shoulders with some skinny jeans and a long black top. (see left) OK! Magazine has more tips here that aren't very kind to Zanessa on make up, poses and frosting.
