I think so! I'll have to ask people with better memories than mine. :D But I don't think she's worn a hat outside of the pilot or the second season premiere headscarf (such an awesome scarf it was, too :D).

Oh, for God's sake, what am I thinking of? ~points to icon~ She wore a fedora in this episode, and it was gorgeous! I even have an image of it on my profile. Tsk. I have to see if I can find caps for it.
