Let's get straight to it — here's what actually matters on this one.

• Use a sturdy, shoulder-shaped hanger — wire hangers distort the shoulder line over time, a common cause of blazers losing their fit.
• Leave breathing room between garments in the closet; compressed storage crushes structure and encourages wrinkling.
• Avoid plastic dry-cleaning bags for long-term storage — they trap moisture and can cause fabric to lose its finish over time.
• Brush down wool blazers after wear before hanging, removing surface dust and helping fibers recover their natural shape.

The fit-and-fabric-health takeaway: Proper storage protects the structure that gives a blazer its fit in the first place — poor storage undoes good tailoring over time.
