Flannel 

Flannel is a must-have for the wardrobe of any gentleman. Whoever wears flannel radiates an air of authority and reserve. Flannel may keep its distance from things, but not from other people.

Flannel suits  offer a high-end look that's perfect for all formal occasions. You can wear a flannel suit to work, weddings, graduations, black-tie dinners and more. Another reason to consider wearing a flannel suit is for warmth. The winter season will inevitably bring cooler temperatures.
