Not so different as one might suspect. I was born human, after all. And I've lived among them-- well, with my clan, but still among humans -- my entire life.

I can't yet speak much as to what clothing is considered fashionable here, but which colors, against what skin and hair, fail to cast one in a deathly pallor... I should think it would hardly change between societies. It's a matter strictly of colors, not cultures.

Perhaps the fabric store would be best... once we find which colors flatter you, we could buy small samples of each, assemble them into something of a book, and then when you go clothes-hunting, you could take that with you for comparison? I do similar with bringing along samples of materials, when I need to match them, though for that, it's often something other than cloth.
