Well there's a fair few answers to choose from here, my favourite being:
What my main issue with this lack of armor is, if the magical laws of the world in which you're playing don't state that iron or metal interferes with magical energies - which would imply that magic is, in fact, some sort of radiation, which is a whole new problem altogether - then why couldn't mages, in their great academies and universities, have been prepared for the outside world and the fact that they may need protecting. I mean an hour or two of physical exercise a day wouldn't go amiss, build up their strength and stamina, to allow for greater running out of danger and to allow them to wear (at the very least) a chainmail vest. The short sleeves can't affect hand gestures, it's not too uncomfortable and not even all that heavy when the weight is distributed evenly over a torso.
So in the end it seems that Furburt [http://www.escapistmagazine.com/forums/read/9.166399#4415377] is right. One guy did it and the others followed. It became a convention and no one wishes to deviate from it.
It does seem the problem is sourced at good old Dungeons & Dragons and that magic being interfered with by iron as well as restrictive armour stopping the wizard from performing all the hand gestures required to cast their spells. It's also been suggested that robes are indeed ceremonial, having been uniforms from the great schools of magic another option is that it's for comfort and warmth, which is understandable since I've worn full plate armour and it is indeed a *****. While it may seem that was what I was implying that mages should protect themselves with, I really meant to say anything more protective than their robes, such as leather armour, the idea of which I noticed was thrown around briefly between some of you.DragonsAteMyMarbles said:Hey, sometimes a mage just needs to feel pretty.
