In that posed photo in the blue shirt, they look pretty perky, almost fake. But that could be one of those Victorias Secret push up tops. Other photos though, they look like they've flattened a bit, they're not being held quite so high.
If I saw a pic without shirt I could tell you in a second if they were real or not. My girlfriend just got implants (never dated a woman with them before), and she spent several months beforehand showing me pictures of other boob jobs and asking my opinion. So I'm pretty well able to tell real from fake.
I say real.
