Vanessa Hudgens may have the most perfect-looking Instagram in the world, but that doesn't mean that she holds herself at a high standard all the time. She definitely had a few off days with her boyfriend Austin Butler post Halloween as she returned her hair color from red to dark brown.

According to Daily Mail, "She's one of the hottest stars on the planet -- regularly pictured looking perfect. But Vanessa Hudgens, 26, traded glamour for comfort while running errands make-up free in LA on Tuesday. The actress wore a baggy black jumper with Make Love Not War emblazoned across the front in large white print."

Looks like Vanessa Hudgens does not mind not looking Instagram perfect 24/7!

This Halloween, she made special time to hang with all her darling "High School Musical" friends to show that she still values friends despite her long-term relationship with Austin Butler.

According to People Magazine, "A few of the High School Musical stars - including Ashley Tisdale, Monique Coleman and Corbin Bleu - reunited to celebrate Halloween on Saturday with the ultimate Disney Channel alum bash hosted by Vanessa Hudgens."

Seeing how Vanessa Hudgens is the queen of dressing up, she must have thrown a wonderful Halloween party.

One of the "High School Musical" dancers Jason Williams left records of their reunion. He captioned one of his Instagram posts, "The crew at @vanessahudgens amazing Halloween party last night! #highschoolMusical #Reunion!!!! #squad #squadgoals #Halloween #hollywood #wildcats."

The host did her fair share of preparing for this year's Halloween by dying her hair red. and her boyfriend Austin Butler certainly stepped up his costume game as well.

And let's be honest. Vanessa probably had a big input on the execution. Vanessa Hudgens maybe a summer babe at heart, but when it comes to dressing up for Halloween, there is no match for her!

But she did need a little getaway to ease into fall style. Good thing that her boyfriend Austin Butler accompanied her to a trip to New York - nothing like the east coast to really get in the swing of fall style!

Her fall style choices have simplified a lot from her bohemian style that she usually flaunts in Los Angeles.
