Return of Reckoning

Considering trying sorc in that tank build which I posted, however the idea of pvping wearing a dress or a swim suit is somehow less then attractive.

So do sorc have any kind of armor which looks like an actual armor, to use as an appearance?

Not that I know of.

There are a bunch of NPC's who mix n match Sorc armour with DoK armour which instantly makes them look much better than pure sorc.

There used to be several cross-class and niche skins on Live, but the official stance on RoR so far has been that these skins were/are effectively just bugged items ~ so these skins likely won't make a comeback, and any broken items (invisible textures, class specific appearance, mismatched item-types, ...) currently in the game will be fixed upon being found.
