Fall weather rarely holds steady for a whole day. A cold morning can turn into a warm afternoon, so the most useful outfits are built in layers you can add or remove. Start with a fitted knit, add a quarter-zip or cardigan for warmth, then finish with a jacket that suits the day's plans.

Start with a slim knit base

A close-fitting knit gives you a clean first layer that sits flat under a jacket. The Soren Mock Neck Sweater has a low mock neck and slight stretch, and comes in seven colors including gray, black, army green, brown and mocha. It looks a little sharper than a crewneck without the full height of a turtleneck.

If you prefer more coverage at the neck, The Lennart Slim Turtleneck Sweater is a slim fit with a little stretch, so it layers under a jacket without bunching. Its listing gives length and sleeve measurements but not chest, so check the men's size guide before you order.

Add a quarter-zip for changing temperatures

A quarter-zip is the easiest middle layer to adjust: zip it up on a cold morning and open it when the day warms up. The Lowell Quarter-Zip Pullover is a slim ribbed knit in ten colors, sized S to 5XL. Wear it over a tee on weekends, or over a collared shirt when you want a neater look.

Choose a cardigan with some structure

A cardigan works as a light jacket indoors and a warm middle layer outside. The Fletcher Shawl Collar Cardigan pairs a cable knit with a shawl collar and button front. It is cut slim with no stretch, so compare the chest measurement with a sweater you already like before choosing a size.

For a heavier option, The Lodge Chunky Knit Zip Cardigan has a full zip, pockets and a chunky knit that can stand in for a jacket on milder days. It is listed as 100% acrylic, hand wash cold, in sizes XS to 4XL.

Pick one jacket for the day's plans

Your outer layer usually sets the tone of the outfit, so choose it based on where you are going.

• Everyday errands: The Calder Patch Pocket Jacket is a button-front jacket with patch pockets and a classic fit. It sits easily over a tee or a mock neck.
• Texture and color: The Tanner Corduroy Button Jacket comes in nine colors, from black and khaki to dark green, pastel blue and lavender. Corduroy adds texture, so keep the rest of the outfit plain.
• Evenings out: The Rocco Faux Leather Jacket is a slim zip jacket in a wide range of colors, including fleece-lined black, khaki and brown, with sizes running to 9XL.
• Colder days: The Ingram Plush-Lined Longline Coat adds length and a plush lining for the coldest mornings. Leave room for a knit underneath when you choose your size.

Keep the bottoms and shoes simple

With texture on top, relaxed bottoms keep the outfit comfortable. The Wade Drawstring Jogger is a loose-fit jogger with pockets that pairs well with a quarter-zip or zip cardigan. For a wider leg, The Cody Vintage Wide-Leg Jean has a vintage-look finish in green or black. Note that it is listed as 100% polyester rather than cotton denim.

Finish with Men's Lace Up Ankle Boots in black, gray or sage. The low heel and lace-up front work with joggers, wide-leg pants and jeans alike.

Check the fit when you layer

Every extra layer takes up room. If you plan to wear a jacket over a chunky knit, compare the jacket's chest and sleeve measurements with a jacket you already own, and allow space for the sweater underneath. Sleeves should still reach your wrist when you bend your arm.

• Cool morning: mock neck, patch pocket jacket, joggers, ankle boots.
• Dinner out: slim turtleneck, faux leather jacket, dark pants.
• Cold weekend: quarter-zip, longline coat, wide-leg jeans.
