Treat denim like midlayer armor

Transitional weather is denim's best season. A jacket or trucker sits easily over tees and under wool coats, then comes off when the afternoon opens up. Choose a wash close to your jeans for a long continuous line, or contrast light and dark for a sharper break.

If you're wearing denim on denim, vary the weight. A softer shirt-jacket over rigid jeans looks intentional; matching stiff weights fight each other. Finish with a knit scarf or lightweight leather sneaker so the outfit doesn't tip into costume.

A morning-to-evening swap

Start with a tee, denim jacket, and straight jean. At lunch, drop the jacket into your bag and add a lighter overshirt. By evening, put the jacket back on over a knitted polo. Same core pieces, three temperatures covered.
