Firstly, never have your suits dry-cleaned. Instead, have your suits steamed and brush it gently to remove any dirt or dust. Unless you spill red wine or drop a meat pie with sauce on your suit, never have it dry cleaned! Dry cleaning is the fastest way to ruin a suit, even more so if it isn’t 100% wool. If you need to travel for business, hang the suit for the flight. If that’s not an option, keep it in a suit bag. When you arrive at your destination, immediately hang the suit in the bathroom, run the hot water for 5 mins with the door shut and the fan off. Leave the suit in the steam with the door shut for 5-10 mins to remove the wrinkles.
