Happy Halloween! This most hallowed of holidays has luckily fallen on a Thursday this year, so our favorite celebs are sharing some special snapshots of the most memorable costumed moments from the past.

Super heroes, convicts, Napoleon Dynamite— we've got a little something for everyone!

Khloe Kardashian Odom posted a vintage family photo on Instagram with the caption, "TBT I stole this pic from @kourtneykardash @krisjenner is giving me her best geisha face, I'm a little lady bug and I'm not really sure what Kourt is dressed as. Either way she's a cutie!!!"

Kourtney Kardashian shared the same photo on Instagram with the caption, "Vintage Halloween! My best friend since I was two, little baby Koko and our mommies."

In the snapshot, a pint-size Khloe and sister Kourtney pose with mama Kris Jenner and two other friends, decked out in their Halloween costumes.  Too cute!

Aly and AJ Michalka posted a blast from the past on Instagram with Miley Cyrus! The sisters were dressed in their Halloween best, but it's the "Wrecking Ball" singer who caught our eye. She was rocking elaborate face paint, a spiked necklace and a sexy black bustier. Miley always seems to make a statement on Halloween, and this year's Lil' Kim tribute is no exception!

Jimmy Kimmel also got into the Halloween spirit! He posted a pic from his childhood on Facebook with the caption, "Happy Halloween! Jimmy and his sister in Brooklyn, New York - 1976. #ThrowbackThursday #tbt."

Cindy Crawford posted a sexy homage to "Grease" on Twitter with the caption, "#TBT: Rande and I about ten years ago as Danny & Sandy from Grease at Herb Ritts' Halloween party! Happy Halloween!"

We love Nicole Scherzinger's Halloween throwback! She posted a pic on Facebook as a pint-sized cutie with the caption, "Happy Halloween!! Here's a pic of me at 7 years old, dressed up as Carmen Miranda!! Chica Chica Boom Chic!! #TBT"
