Guild Wars 2

The search gave me nothing on this,so if i missed it,i apologize.

Anyways,in PvP i get the default PvP set,which is called the Guild Armor Set.Now i wanted to get the same look for PvE,but the Guild vendor only sells the chest piece.The other are(drag) is red if i try to put anything else there.
Is that a bug or intended?If it is not a bug,any idea where i could find the other parts?

If I’m recalling correctly, the guild armor set is essentially another armor set with the guild emblem upon the chest.

Looking here, we can see that the light guild armor correlates with the Devout set, the medium armor correlates with the CM dungeon set, and the heavy armor correlates with the Banded set.
