The 4 Must-Have Pieces for Fall

The Tan Trench: Evening

Take a frothy skirt (Repetto, $128) and rosette-trimmed top (Sportmax, $115) and adopt the habit of flinging a trench (Martin + Osa, $170) over evening clothes for a nonchalant mix. This coat's lustrous fabric is dressy-looking and supple: "I'm learning to extend the trench's range by playing with it," Denise says—wrapping, belting, tweaking the collar and sleeves. A creamy palette keeps the outfit unified.
