Guinan dons two hats, if I recall correctly (pictured below). My question is: are these hats something special to El Aurians, something special to 24th century bartenders, or something else? I don't recall ever seeing anyone else wearing either type of hat in TNG (and I've seen it all now!). I've noticed that both hats completely conceal the top of her head, but I don't know if that's significant.
