Shoutout to the 5-year-old who grew out her hair for this 'Harry Potter' Halloween costume

The parent of a precocious little girl says she spent two years growing out her hair in anticipation of her dream Halloween costume: Harry Potter's Albus Dumbledore. It was definitely worth the wait.

Reddit user jackthlion shared a photo of his five-year-old daughter on Wednesday sporting a fake beard and near-waist length hair to pull off the look.

For all of you non-Potterheads, Dumbledore is the beloved headmaster of Hogwarts in the Harry Potter universe. He's known for his long, flowing hair and his even longer beard.

If you're wondering how a 3-year-old might find out about Dumbledore, jackthlion wrote in a comment that she learned about the character while watching the first Harry Potter movie with her older siblings.

"Her knowledge is just hand me downs from her siblings who are really into it and have been various characters for halloween/school book character days," jackthlion explained.

Despite how little she may know about Dumbledore, her sustained commitment to the costume is admirable. This magical costume is sure to be the envy of every Harry Potter nerd on the block.
