Well, you're more advanced than me in Japanese, it seems, but I would risk something like: I wonder if she's well-born, (because) in some respects, she's classy (refined/elegant).
Let's see if my experience of reading many different languages has some use with a difficult Japanese sentence... (actually we study almost exactly the same number of words and kanjis, it seems)
Hi Nicolas! Thanks a lot for replying, appreciate it..
That's really good and makes perfect sense, being "well-born, rich" - I was actually thrown off by the 生まれ. I was being very literal, thinking "good birth", like normal birth, not Cesarian section, etc. LOL! But of course, almost the same idioms exist in many languages, though..
Actually, my Japanese is really bad, I'm just trying to learn as much as possible from renshuu and some books.
Good luck in your studies, also, if you're taking the JLPT!
