Fall will arrive soon, and in turn, so will that “back to school” feeling. And with that feeling comes the seasonal bug to shop for new wardrobe staples—especially some fresh new denim for those crisp mornings when the leaves begin to change color. The beloved fabric seems to have taken a more important place in fashion this season, as well, as fashion houses like Calvin Klein, Christian Dior, Gucci, Stella McCartney and Olivier Theyskens have incorporated denim into their collections, and in turn, have provided us with more cuts and washed to choose from once the weather turns. Since there is such an abundance of good pieces on the market, we've narrowed it down to the nine trends of the season that you need to know, including high-waisted jeans, overalls, and even the classic Canadian tuxedo. Here, your ultimate fall denim guide, as modeled by Marvel superhero, Pom Klementieff.
