Yep, that's the cape slot and that's just reminded me that Swen did confirm capes when I was in Ghent though I don't recall seeing one in action.
And I'm afraid I didn't notice what that slot third down on the right is, but it seems reasonable to assume it's for a belt and can be magical given it's just above the other accessories. Though as you say, also just under the camp clothes/shoes so inconclusive!
Isn't that the underwear slot? It looked like an underwear slot to me, and since reddit and the forum asked larian for this.
