I met a girl that had ants tattooed going up her leg from just above her knee, wrapping around the thigh, and disappearing into her panties. From afar (more than a few feet), they looked more like a dotted line. Up close, I was able to figure out that she had ants in her pants.
My wife had a tattoo of a daisy chain (the meadow kind, not the adult kind) around her ankle and a tattoo of a rose bud on her thigh. Neither were overt.
