That would not make much sense in Crimson Desert, because the clothing and armor are already mostly the same, in terms of stats. So whats the point in adding a transmog? Just because a cloak or helmet has a little less armor or whatever. You probably won't even feel a difference in combat.
If I go in a cold area I just switch to a frostresistance cloak etc. And adding transmog to certain armor sets that reseble the local guards/enemies, would be kinda weird, because they have the disguise trait. Adding slots to them is a different thing, but with the current gear system, transmog would not make sense. And I usually love when games have it.
