We’re all well aware by now that skinny jeans are timeless and ageless. Some of the most stylish celebrities over age 40 are proof of that. The thing about women in this age group is that they’ve honed their style over the years and know what works (and doesn’t work) for them. For that reason, it’s wise to follow their lead and build your own arsenal of skinny-jean outfits inspired by them.

With those years of sartorial experience under their belts, it’s evident that celebs over 40 have learned which style “mistakes” to avoid and which to make on purpose. (That said, “mistakes” are certainly subjective, according to your personal style.) You’re probably ready to just see what those avoidable, yet chic, “mistakes” are, so keep scrolling to see how celebs like Cindy Crawford, Jennifer Lopez, and Kate Moss master wearing skinny jeans.
