Why did she change her look?
The first reason, and probably the most naive one, is that Valeria Lukyanova was obsessed with Barbie dolls and that her obsession went a little further than usual. However, this is highly unlikely since Valeria didn’t talk much about that. She, indeed, said that she liked playing with dolls in childhood, but who didn’t?
Another possible reason is that she wanted to grab a man’s attention. Again, we can’t know for sure, but again, it’s doubtful, especially since she had her breast implants after she got married. If she already had a man, why would she want to be attractive to other men?
