I just got my Catwoman PF (not EX) statue today. This is my first foray into the world of these huge PF statues and OMG she's gorgeous and I'm already thinking about where I'm going to make room for the next three or four of them. I got #99/4000 and I see one flaw, and that is a tiny chip in the sculpt at the top of her left boot, but it's not enough to make me want to return it. Everything else is flawless.
For those that are talking about the white specks on the suit, I think I may know what you're talking about and seeing. I might be seeing a little bit of that around her right shoulder where the suit is stretched really tight. The suit appears to be a vinyl catsuit. This is essentially spandex with a vinyl coating. If your GF has a full scale vinyl catsuit, you will see the same thing with it over time. You will really see this with any kind of coated spandex, for example the "metallic" spandex does this as well. The issue is that the spandex stretches quite a bit, but the coating can only stretch so much. Any coated spandex is a very fragile material and will break down over time. What you might be seeing are points where the spandex has stretched further than the coating was able to. Granted, this is just my wild ass guess based on the past few pages of posts I've read and based on what I've seen with the same or similar material in full scale, and I have not read back far enough to see actual pictures of the white specks, if such pictures exist.
