Kylie Jenner and BFF Stassie Karanikolaou love to match — but this time they’ve gone the extra mile.

The besties took twinning to new heights in an Instagram photo they both posted Thursday night, in which it’s nearly impossible to tell them apart.

Not only are the friends wearing the exact same flesh-colored catsuits and matching Skims waist trainers ($68), but Jenner and Karanikolaou also made sure to install exactly the same waist-length chocolate brown hair extensions.

It’s unclear if their eerie doppelgänger moment is for a photoshoot of some kind, but Kylie and Stassie seem to be wearing the same makeup look as well, potentially hinting at a Kylie Cosmetics reveal.

Fans were taken aback by their twinning. “This is creepy how y’all are actually clones,” one person said. “Who is who,” another wrote.

It seems the Kardashian family approves; Kim and Khloé both commented on the post calling Jenner and Karanikolaou “twins,” while Sofia Richie said, “SNATTTTTTCH.”
