Fall's wide-leg jeans come in dark wash, rinse, chocolate brown and a few curved barrel shapes, and they look best with a fitted or boxy top. Start with the wash you are most likely to wear. Frame's brown Le Slim Palazzo jeans, Citizens of Humanity's light Ayla Baggy jeans, Alaïa's pastel pink wide-leg jeans and Nili Lotan's black Terese jeans show the range.

Dark denim looks polished enough for the office. Agolde's dark Ren Long jeans and Loewe's black wool blazer make a sharp base, with Manolo Blahnik's houndstooth Gosta ankle boots and Chloé's raffia Summer Banana bag.

Brown denim is a good change from blue, and it sits naturally with cream. Deiji Studios' dark brown Pocket jeans and Allude's cream mock-neck cashmere sweater are a warm pairing, and Tod's tan suede loafers and Marni's brown Bauletto tote keep the palette consistent.

A boxy tee and a leather jacket is the classic street style formula. SLVRLAKE's white frayed Grace jeans and Sacai's black cotton tee go under Arma's chocolate leather jacket, and Le Monde Beryl's taupe suede Claudia flats keep it grounded.

A lighter wash looks dressier with a pump. Mother's light Lemon Twist jeans and La Ligne's striped poplin shirt make a crisp base, and Givenchy's black patent pumps and Gucci's black leather belt add polish.

Wide-leg jeans are the easiest denim shape to wear, but the details make all the difference. If you take one thing away, let it be that the hem should almost graze the floor with the shoes you wear most, so decide on flats or heels before you shorten them. A darker wash looks dressier and is easier to wear through fall. We would skip very pale, heavily distressed styles for colder months, which can look summery. Brown denim is worth trying if you already own blue, since it pairs so well with cream and camel.
