Shirts are essential in every man's wardrobe. But how do you know whether a shirt is suitable for a formal or a casual occasion? In this guide, you will discover the main differences between casual and formal shirts and get styling tips to always be well dressed.

A formal shirt, also known as a dress shirt, is usually worn on neat occasions such as work, weddings or business meetings. These shirts have a clean finish, a stiff collar and are often made of high-quality fabrics such as cotton or twill.

Characteristics of a formal shirt:

• Tight fit with neat finish
• Stiff collar, often with boning for extra firmness
• Double cuffs or button cuffs
• Often plain colours or subtle patterns such as stripes or checks
• Perfect to combine with a suit or jacket

When do you wear a formal shirt?

• Business meetings and job applications: Opt for a white or light blue ironing-free shirt with a tie.
• Weddings and formal parties: Go for a classic white or pastel shirt, possibly with cufflinks.
• Dinner parties or galas: Pair with a blazer and neat trousers.

Casual shirts are less tight and more formal in design. They are ideal for a relaxed look and can be worn loose or tucked into trousers.

Characteristics of a casual shirt:

• Softer fabrics such as linen, chambray or flannel
• Looser fit, sometimes with short sleeves
• More colours and patterns, such as checks or prints
• Button-down collar for a relaxed look
• Can be worn open or closed

When do you wear a casual shirt?

• Weekend outings and leisure: Pair a linen shirt with jeans or chinos.
• Casual office outfits: Wear a neat one with a polo shirt underneath.
• Evening out: Opt for a denim or flannel shirt with rolled-up sleeves.
