literally the caster "fantasy" is to wear robes.. same with the tanks "fantasy" is to wear plate.. if you don't like it, then glam it.

i'd rather not have SE change all the caster base sets to be too "out of character"... understand first why it has to be that way.

like others have said, its probably not that the robes look bad, its probably cause its not your style, which is fine. i for one like wearing robes with i'm playing caster, but more often i just wear my casual outfit around LUL
