Pretty much everything Cassandra wears is sublime.
I second that.
My current favorite is the Refined Prowler Mail (I'm not 100% sure it's the right name in english though) which can be crafted. it's a level 3 armour.
(I don't rember where I got it but the wiki says you can get the schematic in a rift loot by the Frostback Basin in the JoH DLC)
If you play as a rogue and that you yearn for some heavier looking armor (I did) it's perfect combined with the Prowler Mail Arms. It's not a fancy armor but I like the roughness/practicality of it (the elves will look a bit sturdier fyi).

I usually pair it with the Ardent Blossom helmet. It gives a vague "Knight of Flowers" vibe but that's more my personnal taste than a badass thing.
As for weapons the Longbow of the Griffon looks great (it looks a lot like the bow version of the Hawke's Key in DA2)
