Couple a' tricky ?s for ya

[Random Axe]

Regarding the following questions come to my mind:
Are there masterwork robes and if so, what do they cost?

My first reaction was that, if the adventurer's outfit was of masterwork quality, then there would be no reason why they wouldnt' be able to be enchanted to grant bonuses. But the cost? RAW states that masterwork armor costs +150 gp over the base cost of the armor. Would that mean a masterworked robe or tunic costs 151 gp?

Maybe.
