A swimsuit competition, which is more commonly called bikini contest nowadays, is a beauty pageant, where the contestants were swimsuits. When the contestants are judged, they are mostly judged if they are physically attractive. Companies have sometimes organised such contests, to promote their products, or to find new models (e.g. for their swimwear).
