It is designed for informal settings and can come in various styles, including short-sleeved, long-sleeved, and button-down options. Casual shirts often feature patterns such as plaid or stripes, making them suitable for everyday wear. These shirts can be paired with different types of bottoms, such as jeans, shorts, or chinos, making them a popular choice for social gatherings, outings, or relaxed work environments. They are a staple in many wardrobes and can be easily dressed up or down depending on the occasion.
