Asymmetrical green pencil skirt ($78; Green can be used as a neutral, as seen all over the fall runways. Style this polished skirt with a suit jacket to add color to your work wardrobe.

Sleeveless trench ($160; This is perfect for these in-between weather months. Throw it over any work look and knot, or shrug it on with a casual weekend outfit with the belt tied in the back.

Combined total cost: $238
