#ThrowbackThursday: Amazing Old School Pics of Celebrities Dressed Up for Halloween

The best kind of throwback pics on Instagram are the throwback pics on Instagram posted by celebrities of themselves dressed up for Halloweens of the past. Are we all in agreement on that? Good. Click through to see some of our favorite old school costume-themed #TBTs from the Kardashians, Emma Roberts, Snooki and more.

Have Mercy! Lori Loughlin shared the most epic Halloween #TBT of all time—when Jesse and Rebecca dressed up as Elvis and Priscilla Presley on Full House.

Khloe Kardashian shared this old school pic of Kiki and Koko from Halloween in the early 90's. Beyond adorable.

And big sister Kourtney Kardashian posted this cute vintage halloween pic of herself, Kris, Khloe, and the girl who she refers to as her "best friend since I was two."

Lisa Hochstein of Real Housewives of Miami recently posted this #TBT pic of her and a friend dressed up as Tinkerbell and Peterpan in 2008 before her Halloween party for Make a Wish foundation. This year, Lisa's hosting the same private, Miami-based party again where all proceeds go to the organization.

If you're wondering, yes, they have Halloween in Australia! Cody Simpson shared this adorable snapshot on his Facebook page of him and his little sis, Alli Simpson.

Kelly Ripa's first ever #throwbackthursday post came just a few weeks ago, where she tweeted this photo of herself and a friend dressed up for Halloween cira 1984. Not sure what that costume even is but she sure was a cutie!

Justin Bieber's manager, Scooter Braun, made a pretty epic Napoleon Dynamite, yes?

Emma Roberts Insta'd this pic recently to promote the new episode of American Horror Story: Coven, but who cares because this is so cute! Emma Roberts as a kid looks exactly like Emma Roberts as a 22-year-old.

Ivanka Trump's Halloween #TBT was doubly sexy, but then again, she looks good is just about anything.

Jessica Chastain posted this photo on Facebook of her and some friends from Halloween 2008. She noted that they bought those costumes in the children's department at Duane Reade!

Snooki shared this gem from her college days on her official blog, calling this costume a "Halloween Hooker." Sounds accurate.
