“I’ve always known warlocks to be interested in seeking power in the darkest of places—and making bargains most people in their right minds wouldn’t make. The Plagueheart Raiment is made of cloth scraps from Naxxramas, fouled with plague and pestilence and left entirely uncleansed, which seems to be the point of it: the source of power that makes the corrupting, painful spells of the warlock who wears it even stronger.”

— World of Warcraft: Exploring Azeroth: Northrend, pg. 149

Plagueheart Raiment is the tier 3 warlock set.

Source

Most tier 3 items can be acquired through quests given by Mataus the Wrathcaster, who can be found in Light's Hope Chapel in the Eastern Plaguelands. Before the quests become active, Echoes of War must be completed.

The quests require several crafting materials, [Wartorn Cloth Scrap]s (which drop from trash mobs in Naxxramas) as well as a token from a boss in Naxxramas

The only exception is the [Plagueheart Ring], which drops directly from Kel'Thuzad in Naxxramas.
