Hmmm, which is worse on influencing a young girl? Britney Spears/ Paris Hilton etc? or THE PLAYMOBIL BIKINI GIRL? lol, tough choice!
In all seriousness, it isn't images in media, or even in toys that will determine a young girl's moral/social practice, but UPbringing that will determine what version of propriety a young girl will subscribe to as she forms her personal moral code. The klicky in and of itself, IMO, is harmless. It's the approach one would take with it that counts, and of course one's own personal level of propriety and discretion (and degree of conservatism) that will affect whether a person would consider this liberal design acceptable or not, socially speaking.
Aesthetically, as I said before, the bendy-looking limbs detract from the traditional blocky klicky look, IMO. I think there would still be a way to make a bikini klicky that doesn't look so much like Poly Pocket.
