Time has a way of changing things — people, places, faces — and it looks like the Kardashian girls are not immune to the ravages of time.

Kim Kardashian posted a photo to Instagram for Throwback Thursday of herself and older sister Kourtney from 1998, when the two were approximately 17 and 18, respectively.

While ageless Kourtney looks nearly the same as she does today — the same deep tan, straight dark brown hair, and subtle makeup — Kim has undergone a significant transformation, from her fashion choices to her facial features. It also seems pretty unlikely that anyone’s caught the reality queen sipping from a Solo cup since.

In the photo, Kim rocks a white tank, strategically faded jeans, and a makeup look that’s … how should we put this? Aggressive. It’s unclear if it’s a facet of aging or a delightful effect achieved with her purple-bronze lipstick, but it seems that, over time, Kim’s lips have actually deflated slightly to the still well-above-average pout she has today. The changes in the rest of her face, however, we’ll just chalk up to “good makeup” and “lots of sleep.”

We definitely think the style Kim sports today, from her designer duds to her lighter locks, suit her better than the teenage mallrat look. As for Kourtney, we think it’s about time to bring back that cowboy hat.

Are you surprised by how different Kim and Kourtney look?
