I think I have seen this girl before, but can't remember where. Maybe she was shot before for a magazine or something. And I think her chest is real, not the result of breast augmentation. I wish I could remember her name.
Update: A reader at my blog id'd her as Irene Fah. Yep, that's her, and yep, they are real. No silicone from what I can see in her unclothed photos (to be found elsewhere, not here, sorry).
