Pants are one of my favorite items to experiment with in the fall and can make your entire outfit pop. These subtle black and blue plaid dress pants are perfect for swapping out your go-to khakis or chinos and adding in a statement piece to your look. I paired the pants with a bright gingham woven and a dark black cardigan to contrast against the white and blue checkered squares up top, but match nicely with the pants down below. The solid cardigan ties all the colors and patterns of the entire outfit together, which is an important factor in making sure you look remains clean rather than chaotic. Cardigans are also a perfect way in the fall to stay warm in an item that adds to your outfit without putting on a heavy coat just yet!
