Make it work for work: Plaid

If you only buy one plaid piece this season, make it this one. Classic workwear combinations such as wide-leg pants and a cashmere sweater are enlivened by the addition of a tailored blazer; finish a modern look with sculptural mules. On desk-to-dinner Fridays, pair it with frayed jeans, stiletto sandals and a waist-cinching belt.

If you like to keep your workwear look fuss-free, you’ll love the prim femininity of a plaid pencil skirt. If you prefer to push the envelope at the office, try deconstructed tailoring or voluminous paper-bag pants. But whatever you choose for the bottom half, balance it on top with slimline knits and crisp cotton shirts.

This season, the Prince of Wales check suit, a cornerstone of the corporate closet, is a certifiable fashion hero. Wear yours with a T-shirt and bright white boots, and you have a decidedly modern, infinitely wearable look. From mini skirt suits to ’70s-style pants, experiment with different silhouettes and power shoulders.
