Preppy wear is a style of clothing that is typically associated with the upper class. It is characterized by its neat, clean, and classic look. Two items of clothing that are commonly associated with preppy wear are polos and POLO shirts. Polos are collared shirts with two or three buttons at the neckline, usually made of cotton or a cotton blend. POLO shirts are similar to polos but have a more casual look, often featuring a ribbed collar and cuffs.
