Weejuns are a type of slip-on loafer that originated in the United States in the 1930s. They are characterized by their moccasin-style construction and a distinctive leather upper with a penny slot on the front. The name "Weejuns" is derived from the term "Westerner," reflecting their popularity among college students and preppy fashion. Originally made by the brand G.H. Bass, Weejuns became a staple in American casual footwear. They are often worn with both casual and semi-formal outfits, making them versatile for various occasions. Over the years, Weejuns have maintained their classic appeal and are still popular today.
