There has been one gift that every woman I've ever known has asked for, be she a friend, girlfriend, relative, what have you: slippers. I'm not kidding. All of them that I have given slippers practically melt when you give them to her. I suppose it's just a flaw in women's brains that makes them feel this way about fuzzy foot wear, but there you go.
You say that she's asian, but only kind of traditional? Tough call, but I'd probably lean towards the fuzzy kind of slipper. Definitely get the kind that is open in the back for easy slipping on and off.
Or, you know, you could get her a nice Christmas
