Skinny Dipping

Skinny Dipping is swimming, but without the swimsuit. In the nude.

Usually, this is used in fiction for several reasons:
 * Fan Service, of course. Because nothing turns people on more than water! Sometimes it's a way to get away with a nude scene without being too erotic.
 * Naked People Are Funny and Gone Swimming Clothes Stolen, of which the latter is a sub-trope. Together, they can make a humorous situation.
 * Sometimes a common element in Slasher Flicks, where a female skinny dipper is usually killed by the murderer.
 * Samus Is a Girl. A great way to reveal her secret, right?
 * To be Truth in Television.

As mentioned above, Skinny Dipping is Truth in Television. It was a common practice back before the 1950s or so, when swimsuits were impractical. It is still done today, though.

Related to Naked People Are Funny. Often the prelude to a Two-Person Pool Party. Can result to Outdoor Bath Peeping or Naked People Trapped Outside. Super-trope to Gone Swimming Clothes Stolen. Contrast Non Nude Bathing. For anime, see also Furo Scene (which is not always naked, only often).
