What is a "dress shirt"?

A dress shirt, also known as a button-up shirt or formal shirt, is a type of shirt designed to be worn with a suit or dress pants in a professional or formal setting. Dress shirts are typically made from a lightweight and breathable fabric, such as cotton or linen, and feature a collar, cuffs, and a front placket with buttons. They may also include features such as a breast pocket or pleats at the back for ease of movement. Dress shirts come in a variety of styles, such as classic, slim-fit, and athletic, and may have different types of collars, such as spread, pointed, or button-down. They are an essential item in many men's and women's wardrobes for formal occasions and professional settings.
