It makes complete sense that the Kardashian and Jenner sisters all look alike seeing as, you know, they're related and everything. But sometimes they look, well, scary alike. As in, we're not even sure which member of the Kardashian-Jenner clan we're looking at — and, weirdly enough, it can be especially confusing on Instagram. After all, all five of the sisters are super close, and though they're constantly posting selfies, they're also always posting pictures of each other, too. Whether it's a birthday message, just showing a lil love, or a completely shameless bit of promo for a family member's project, the KarJenner sisters love throwing up pics of the fam.

And despite each sister's pretty distinct — and often iconic — looks, every now and then we see serious overlap. Whether Kylie Jenner is rocking a short blonde bob or Kendall Jenner is stealing Kim Kardashian's exact eye makeup routine, it's easy to get tripped up. Sometimes, we just simply aren't sure which of the sisters we're looking at — whether it's for a quick second or a full few minutes. Not sure what we mean? Check out this gallery of the Kardashian-Jenner sisters and see if you can tell who is who.
