ELI5: Explain Like I'm 5

Lounge suit

A lounge suit is a type of fancy outfit that people wear to look stylish and formal. It usually has a jacket and pants that match in color and fabric. The jacket is longer than a regular jacket and covers your butt. It has buttons in the front that you can either keep closed or open. The pants are made of the same fabric as the jacket and they are usually straight and tight-fitting on the legs. You wear a shirt and a tie underneath the jacket, and sometimes a vest too if you want to look extra fancy. You can wear a lounge suit to fancy events like weddings or business meetings, or just to look smart and put together.
