Bernd - thanx for calling that thread to my attention. I may spend some time there. But, from a quick check, the ladies didn't look all that slim -- at least, not by my standards, but then, I like 'em skinny.
I'd suggest keeping this thread going, and limiting it to ladies who are both (1) at least as slender, and yet (2) at least as well-endowed, as the two examples below.

Also, this next lady raises the question, "Are these boobs real?" And, this thread should decide whether [obviously] silicon boobs should disqualify any candidates. My suggestion: hell, no, the more the merrier!
