When Heart of Thorns came out, I didn't have a Thief yet and I really wanted to try to get a Daredevil. So I quickly leveled her up to 80 and got the Daredevil specialisation soon afterwards.
With all the trenchcoats in the game it's fairly hard to make up a good looking armor for thiefs (because trenchcoats and thiefs just don't match in my opinion). Finally I found a good looking set, which is this one. It's easy to move in for a thief, and it looks good as well
