Steam your shirt while you shower — the steam removes light wrinkles fast. Always hang shirts on wooden hangers to keep them crisp and fresh.
Use collar stays or a touch of starch spray to keep collars sharp. For button-down collars, iron them lightly after drying.
Tuck using the military tuck, fold excess fabric at the sides for a slim fit. Or use shirt garters to keep it neatly tucked all day.
Choose breathable cotton or linen shirts for summer. Use sweat pads or wear an undershirt to absorb moisture.
Attach a small strip of double-sided tape between buttons for a clean finish. Better yet, go for stretch fabric shirts for comfort and flexibility.
