Maybe i should rephrase it a litle, because i think that the equipment and costumes used by the northmen and most of the knigths and mercenaries in the many hauses of Westeros are ok, really (my personal favorites are the Nigthwatch and the Dothrakis, so the way to go would be a minimalistic design with a lot of leather and fur, perhaps?). The thing is, even at their best, these costumes don´t look particulary
that good either. And when they fail, they fail big. Like with the Lannister helmets, or those guards at the gate of Qarth. And more recently, of course, these Unsuiled.
Those are the designs that really stick with you.
Which creeps me out the
most, you mean
