That's not realistic. Not one statue I have ever gotten has not had some small problem with it. What's to guarantee he will get a better one?
I just find it ridiculous people are even calling it a problem. If that is considered an issue or flaw then there aren't perfect pieces. Something that minor is almost not even noticeable and it is obvious her underwear was an afterthought in general for the piece. It should never even be seen when on display.
