Every man should own at least one classic, versatile suit that can be worn in a variety of different situations. The most common and versatile style of suit is a single-breasted two piece suit with two or three buttons. This style of suit is characterized by its clean lines and simple, uncluttered silhouette. It is typically made of wool or a wool blend and is available in a range of colors, from classic black and navy blue to more modern shades like charcoal and grey. Other styles of suits that every man should consider owning include a double-breasted suit and a three-piece suit. Both of these styles are more formal and are suitable for special occasions or business meetings. Ultimately, the best style of suit for you will depend on your personal style and the occasions you plan to wear it.
