Imoen and Nalia are almost identical, they're both dualclass mage/thiefs. Nalia switched to mage at level 4, Imoen at 7. But their ingame paperdolls/avatars look different, Nalia looks like a mage (wears a dress), Imoen as a thief (wears "thiefsuit"). If they put on a robe, it's properly displayed for Nalia but not for Imoen.
I think Imoen should be displayed like a mage, just like Nalia is, or at least Imoen should be able to display a robe. Agree?
