Jacket Button Rules: Sometimes, Always, Never

Two-button jackets: button the top when standing (sometimes above), unbutton when seated; never button the bottom. Three-button: always button the middle, sometimes the top, never the bottom.

Double-breasted jackets typically remain buttoned at the working button, though JEREMIAH SUIT suggests unbuttoning when seated for comfort and clean drape.

These rules stem from history and cut logic—the open bottom button allows better movement when walking. JEREMIAH SUIT fittings confirm button placement for optimal waistline when fastened.
