A lounge suit, also known as a business suit or sack suit, is a conventional and versatile type of suit worn for business or semi-formal occasions. It typically consists of a jacket and trousers made from the same fabric. It's more relaxed than formal wear but still conveys professionalism. Think of it as the everyday uniform of the business world. The jacket is usually single-breasted with notched lapels. The trousers are typically straight-legged or slightly tapered. Lounge suits can be styled with various shirts, ties, and shoes.
