A Young Kendall & Kylie Jenner Halloween Costume For You & Your BFF — PHOTOS

Reality TV's most famous little sisters are definitely two of the hottest stars in the world right now, but how about throwing it back to when they were the cutest? Grab your best friend or your sister to create young Kylie Jenner and Kendall Jenner halloween costumes, because it's been a while since we've gotten to lay our eyes on the adorable, devious little troublemakers they once were on the early seasons of Keeping Up With The Kardashians. Oh, how things have changed.

When the first episode aired in October 2007, Kendall was almost 12 years old, and Kylie was just 10 — practically babies, compared to how old they seem (and look) now. The show's original 23-second title sequence reminds us just how long this show has actually been in production, because man, those clothes seem old. I mean, Kris was wearing a satin babydoll minidress. Huh?

Kendall and Kylie's outfits, though seriously outdated now, definitely conveyed their fun, cheeky attitudes with leopard, sparkles, and of course, the sassy hands-on-hips pose. No wonder they're both modeling now.

Here's what you need to pull off the perfect young Kendall and Kylie halloween costumes. Those who get it will get it — and love it. Don't forget to strike this Charlie's Angel's pose, too:

Or just go with the classic hands-on-hips. (And hey, if there are at least 6 more, why not go for the whole family?)

Here's your old school Kendall & Kylie costume kit.

Kendall Jenner

Start with a strapless leopard print dress...

Leopard Strapless High Waist Party Dress, $33, May Kool

And add a gold statement necklace to mimic the center halter strap.

Gemma Simone Gold-Tone Statement Necklace, $34, JCPenney

Top of the look with a pair of sweet gold ballet flats.

Ballet Flats, $5, H&M

The best part? You could definitely repurpose that jewelry after Oct. 31.

Kylie Jenner

When's the last time you saw a sequined gold tube top? Rightttt now.

Gold Sequin Tube Top, $17, Sequin King

Can't forget the ruffled leopard skirt either! (I mean, doesn't everyone already have one of these?)

Brown Leopard Skirt, $9.99, lollicouture

Pair with the same gold flats as Kendall, just like on the show (aww, twinsies.)

Name Tags

Office Depot® Brand Name Badge Labels, $5, Office Depot

Just like in the title sequence, add some name tags to your costumes so that it's completely obvious who you and your friend are trying to be. I'm sure it's not 100% needed, but it'll make the costume that much more hilarious.
