A swimsuit competition is when people wear special clothing called swimsuits to show off their bodies to judges and other people. The swimsuits are usually very colorful and pretty, and they show off parts of the body like the arms, legs, and stomach. People who participate in a swimsuit competition often exercise a lot and eat healthy so that they can have strong muscles and look good in their swimsuits. The judges give points to the people who wear the best swimsuits and look the best overall. The competition is usually held as part of a bigger event, like a beauty pageant or a sports competition.
