Female swimming was introduced at the 1912 Summer Olympics. Competitors from 17
countries took part, with women from nine countries wearing swimsuits similar to
Kellerman's swimsuit, which were similar to swimsuits worn by the male swimmers.

short sleeves on top.
The name "swim suit" was coined in 1915 by Jantzen Knitting Mills, a sweater

bathing-suit day at New York's Madison Square Garden in 1916 was a landmark. The
swimsuit apron, a design for early swimwear, disappeared by 1918, leaving a tunic
covering the shorts.
