Swim wear

“There is no special etiquette in bathing except that a woman’s bathing-dress should not offend against modesty. It is absurd for her to wear a dress that will hamper her movements in the water, but it is far worse to wear a garment so attenuated that general attention is attracted to her when she goes down to the water and comes out of it. There is no set rule as to what kind of dress should be worn. It depends entirely on the individual. A well-bred woman is her own best guide in the matter.”
