Korea, Japan and China are the major countries in Asia. You tend to see models and actors from those countries more often then other countries. Which is why most people will say those countries have the best looking ladies.
Remind me of a time when I use to watch dubbed Kong-Fu movies on Sundays back when. This Korean actress had C cups. My mother came over and looked at the TV for a bit. Then she said, 'That woman had a boob-job'. Then she left the room. Of cause I counldn't say, A, B and C cups are normal boob sizes for females'. Well, at least not when your 14 to your mother.
