learn_russian | since we're talking tattoos...

Of which I have a few...
One of my ideas for a tattoo is an (artistically rendered) letter ж. For two reasons basically, one because it's the most beautiful letter in the russian language both in sound and appearance and could make a really great tattoo. The other is the basis for my question. I'm under the impression that ж could be understood as a kind of shorthand for "woman." This comes mostly from a couple of moscow cafes I've been in that had just ж on the door of the women's bathroom. However, it's also possible that that's just shorthand for "ladies' room" and in that case I wouldn't necessarily want that as a tattoo...am I wrong to understand this letter as a symbol for women in russian? If not, is there one? Feelings about tattoos in general aside, what would a native russian speaker percieve as the meaning of such a tattoo?
