No, some look quite natural.
When I was in Saks a few months ago, the woman helping me had stunning cleavage. It isn't something I typically notice but she was quite arresting.
I told her :floorlaugh: and she told ME that she'd had implants and that she had flown to CA for some renown plastic surgeon who was expert at it. She actually stepped closer and said, "Do you want to touch them? No one can believe how natural they feel."
NO, lady, I don't want to touch your boobies!! Jesus God no.
I just said, "I believe you" and took a step backwards. :floorlaugh:
Hers looked really, really great.
