In a New England winter, your coat is the outfit. It is what people see from November to March, and it does more work than anything else you own. Buying one well is worth the time.

Fabric First

• Wool is warm, durable and holds its shape. A high wool content will be warmer and wear better than a blend heavy in synthetics.
• Cashmere and wool-cashmere blends are softer and lighter, but more delicate.
• Down is the warmest for its weight. A tailored down coat or a long quilted parka is often more practical in deep cold than wool.
• Weatherproofing matters in snow and sleet. Look for water-resistant finishes or shells.

Fit

Try coats on over the thickest sweater you plan to wear. Lift your arms, reach forward as if for a door, and sit down. The shoulders should sit at your natural shoulder, the sleeves should cover your wrist with your arms bent, and it should button without pulling across the back.

Length

Knee-length is the most versatile for most people and covers a jacket. A longer coat is warmer and dramatic but harder in and out of cars and on public transport. A hip-length coat is easiest to move in and best with trousers.

Construction Details

• A full lining that lets the coat slide over layers.
• Well-attached buttons, with spares sewn inside.
• Pockets deep enough to hold gloves and a phone.
• A collar that can be turned up against wind.

Color

Camel, navy, charcoal and black work with everything. If you own only one good coat, choose one of these. A second coat in a color you love is a pleasure, not a necessity.
