Criminally overdressed, IMHO.  The "skinny-dipping in someone else's pool" is a classic trope that I haven't figured out how to update OR genderflip (no girl would go skinny dipping if the guy starts first... because they're the smart, sensible gender and don't think with their privates).

And you know what, we don't actually see her jump in, I wanna see that!  The body hit the water, the splash, the reaction... that's the fun of it.
