What is a "bush shirt"?

A bush shirt is a loose-fitting, lightweight shirt typically worn in warm or tropical climates. It is designed to be comfortable and breathable while providing some protection from the sun and insects. Bush shirts are often made of lightweight fabrics such as cotton or linen and may feature short or long sleeves, a collar, and a button-up front. They can be worn for outdoor activities such as hiking, camping, or safari, and are also popular casual wear in some cultures. The name "bush shirt" may have originated from its use by British colonial officials in Africa during the 19th and early 20th centuries.
