You don't need to overhaul your closet this fall. Any of these items will do the trick.
1. Quilted Vest
On brisk days when a coat would be too much, layer a lightweight down vest over or under a suit. Victorinox ($195), swissarmy.com.
2. Horn Glasses
Shoes make the outfit. Sunglasses make the man, especially when they're carved from real buffalo horn. The Elder Statesman ($2,800), elder-statesman.com.
3. Tonal Blazer, Shirt, and Tie
Ditch the conventional dark-suit-light-shirt combo for rich layers of intense blue, the new navy. Blazer ($1,275), shirt ($325), and tie ($175) by Calvin Klein, calvinklein.com.
4. Navy Duffel
This handsome leather carryall is inconspicuous luxury, which is the preferred kind these days. Louis Vuitton ($3,390), louisvuitton.com.
5. Cashmere Sweater
This understated striped crewneck looks sharp with a blazer or banged-up jeans. Brunello Cucinelli ($895), brunellocucinelli.com.
6. Blue V-Neck
An overdyed indigo T-shirt looks as fresh with a plaid shirt as it does on its own. G-Star ($80), g-star.com.
7. Cavalry Boots
Nine-hole boots with smooth, unadorned toes can easily anchor a pin-striped suit or a pair of cords. Z Zegna ($650), zegna.com.
8. All-Black Watch
This discreet timepiece can make even a five-year-old suit seem current. Nixon ($90), nixonnow.com.
9. Cashmere Jeans
No matter how many times you wash your favorite jeans, they'll never feel as good as woven cashmere. Naked & Famous ($230), nakedandfamousdenim.com.
10. Spiked Wallet
The raised surface of this wallet lends it just the right touch of punk. Balenciaga ($395), 212-206-0872.
