Definition & Meaning of "slacks"

What are "slacks"?

Slacks are a type of tailored pants that are often worn as part of a formal or business-casual outfit. They are typically made of a lightweight, durable fabric such as wool, cotton, or synthetic blends, and feature a straight cut that falls from the waist to the ankles. Slacks are usually flat-fronted, without pleats, and can have a variety of pocket styles, including front slash pockets, back welt pockets, or side cargo pockets. They may be worn with a dress shirt and tie for a formal occasion, or with a more casual shirt or blouse for a business-casual setting. Slacks are a versatile wardrobe staple that can be dressed up or down depending on the occasion.
