she is also one of the latex boob shirt girls in some of the pics you can see the trademark raised collar bone in them.

Here we go with the collar bone.
While having a raised collar bone is not unusual for any fit girl, I'm not sure I get the drift here. If you do a search of huge fake boobs, you would see most have noticeable collar bones. Even Beshine had very visible collar bones 10 years ago before her boob expansion rose to the point where they nearly start at collar bone height, obscuring it almost totally. I think, for the most part, it is all about how fit a girl is; you don't have to look any further than Pandora Peaks to see both fitness and collar bones. Girls with big natural boobs may have a little extra, so their's may not be so apparent.
The drift is that the manufacturer makes the prosthetics with a specific kind of collar bone look and that is it.
Ah, yes, I get the drift; the prosthetic would normally hide the clavicle, so it is built in to give the impression of both real and fit. Nice that they think ahead in trying to make them look as real as possible; I still can't get over the matching skin tones. You may not pass wearing a bikini, but with a little makeup to blend the neck, you could likely go anywhere and pass for real; sure would have me looking, ok, staring.
