OK. First of all. It's a PLAYBOY party, so she was probably "theme-dressing".
Secondly. Why do we expect her to dress any better now than she did back in 1994?? Does anyone remember those HIDEOUS costumes??
Thirdly. I think it's the makeup/lighting combination that makes her look old.
Fourth. She appears to be in FABULOUS shape. If you've got it, why not flaunt it? Admittedly, you could flaunt it in a slightly more tasteful manner, but nonetheless this is far from the worst I've ever seen in this genre.
I am OBVIOUSLY in a minority opinion here, but I don't see what all the shrieking is about, really. And I have NEVER been much of an Oksana fan.....
