Mustache styles vary widely, each offering a unique look. Common styles include the Chevron, characterized by a thick, wide shape that sits above the lip, and the Handlebar, which features long, curled ends. The Pencil mustache is thin and neatly trimmed, while the Horseshoe resembles an upside-down U, extending down the sides of the mouth. Other popular styles include the Fu Manchu, which hangs down past the chin, and the Walrus, known for its bushy appearance. Each style can reflect personal taste and cultural influences, making mustaches a versatile aspect of facial hair grooming.
