It is illegal for a man to wear a swimsuit that exposes his legs too much in public.

The Law Explained

Kenosha once had strict modesty laws governing beachwear on the shores of Lake Michigan. Male swimmers were required to wear bathing suits that covered their chests and extended a respectable distance down their thighs to avoid offending public sensibilities. The arrival of modern board shorts and swim trunks eventually rendered this prudish law obsolete.
