Brelm Blazon's: There is Noble's Outfit and Fine Outfit. The former costs 117, the latter 135. Both have got the same description. The former, though, the cheaper one, gives +1 to buff and persuade, while the latter gives nothing. A noble guardsman tunic costs 166 and gives nothing, even the description is the common one. Other than that, some other no-bonus garbs are considerably more expensive than the skill-increasing ones, and they haven't even got a cooler description.
Merchant price inconsistencies
Maybe the merchant didnt know what he had on his hands. Then you come walking up with a keen fashion sense.
Fixed, thoroughly.
