The winters are long in Russia.
And this red-haired 40something is out, naked with her whole body glistening with water, in one.
No matter that it's a bright, sunny day -- you can tell by the look on her face, if not where and how she has her arms and upper legs (in that she might just be modest), that she's freezing slowly.

If this picture is a joke, then someone has a sick sense of humor.
