Men wear vests in autumn, unlocking the "hidden code" of decency and gentlemanly demeanor (2)

Three different styles of vest wearing.

Gentle style: corduroy vest + round neck sweater + straight pants

Light khaki corduroy vest (choose fine corduroy to avoid looking bulky), paired with an off-white round neck wool sweater (choose an 18-gauge fine knit sweater to avoid looking bulky), and charcoal gray straight-leg casual pants (the trouser legs are rolled up 2cm above the  ankles, revealing off-white mid-calf socks)

Clever style: linen vest + denim shirt + overalls

Dark olive green linen vest (the slightly wrinkled texture brings a sense of casualness), paired with a light blue denim shirt (the cuffs are rolled up to the forearm to reveal the watch), and paired with black overalls (choose a straight-leg style with untied trouser legs). Pair it with white sneakers and a dark gray wool baseball cap—the breathability of linen is perfect for autumn afternoons, and the formality  of the vest offsets the ruggedness of the overalls, creating a stylish yet understated look. It also adds a thoughtful, gentlemanly touch to any outfit for men over 30—after all, true respectability isn't about expensive clothes, but about getting the right fit.

Don't layer too bulky: For autumn, choose a thin sweater or knitted shirt as your base layer, avoiding thick hoodies or turtlenecks. Otherwise, the vest will look like it's clinging to your body, losing its sharpness.

Bonus details: A harmonious connection between your vest and accessories.
Don't put pens in your vest pocket (retro and practical), wear a thin silver watch with a strap (dial diameter ≤ 40mm to avoid overshadowing), and choose a dark brown leather briefcase (the color should match your vest or shoes).
Tip: Button your vest to the top two buttons (never leave the bottom button unbuttoned). Unbutton when sitting and button when standing—this is the "invisible etiquette" of gentlemanly attire.
