Knight Mail Transmog Set

On my hunter, I have a transmog set that looks like plate. Not so coincidentally, it happens to be my pet-tanking set.

The base components of this set are from the "Knight's" set:
Knight's Breastplate
Knight's Legguards
Knight's Boots
Knight's Gauntlets
Knight's Girdle

The true gems are from other sets however:
Champion's Helmet
Ornate Pauldrons (shown) though if you want a softer look, the Ancient Pauldrons are nice.
Gossamer Cape

Now come your accessories and trimline:
Ranged - Wolfslayer Sniper Rifle (shown) though Rifle of the Platinum Guard is a very close second.
Tabard - Stormpike Battle Tabard (shown)
Shirt - White Tuxedo Shirt (shown).  The shirt does show through in many places.
Bracer - Any bracer. Color can show as a short banded cuff above the gloves.
