How to Wear: The Soft Trench
As comfortable as a bathrobe—but far more stylish—the latest trenchcoat is easy, relaxed, and the perfect layering piece. Try it with loungewear for a casual-chic weekend look, or belt it loosely over a dress for evening.

How to Wear: Plaid
The print of the season is plaid, but there's nothing schoolgirl about these checks. The most modern way to wear them is to mix your patterns. Just remember to keep everything in the same color family, and vary the scale of each print so the look's not overwhelming.

How to Wear: Knits
Sweaters aren't just for casual days anymore. Instead of pairing them with your usual jeans and boots, try them with dressier skirts and tops—I love the contrast of plain and fancy in these looks.
