Cloak: Yule Hoodless Cloak
Chest: Elven Hauberk dyed navy
Hands: Elven Cloth Gloves dyed navy
Feet: Grimkell’s boots dyed grey
All items are easily available with the exception of the Cloak which was from the Winter Festival. Although the boots are a quest reward I believe you can get a similar, if not identical, pair at the outfitter’s in Bree.
