Most other classes have armor with a base AC higher than what clothes add, and thus are limited to other pieces with the same base AC that aren't wildly different in appearance. The clothing pieces in NWN, the ones with no base AC, are very different from each other, especially with the content from the CEP added. There's less of a need to restrict the heavier armors because the options for appearances are basically the same, unlike with clothes. But I can assure you that it isn't just monk robes that have these partial appearance locks, they're just the only things you've noticed.
Ah, now that makes perfect sense! Sorry for being so persistent, I so hate not being able to get something. Thanks for the patience and this one last reply though
