The Set
Head: [Cowl of Absolution] (BoP)
No alternatives. This color/model combination is only available for Priests.
Belt: [Astralaan Belt] (BoE)
Drop Chance: 0.4%
Alternatively, [Cincture of Polarity] fits right in with the lines of the chest piece and a tad easier to get as it's a boss drop from Naxxramas (10M).
Chest: [Black Velvet Robes] (BoE)
Drop Chance: 0.1%
Alternatively, [Silver-Thread Robe] (BoE) is a sleeveless version you can combine with the Stylish Black Shirt. It's not any better with the drop rate, though.
Shoulders: [Flameseer Mantle] (BoP)
Drop Chance: 25% chance from Galgann Firehammer (Uldaman)
Alternatively, [Batwing Mantle] has a 27% drop rate from a rare elite in RFK. [Darkcloth Shoulders] is a BoE available via an Inscription quest.
Hands: [Hands of Eternal Light] (Sunwell BoE pattern; not pictured in screenshot, but it's not class-restrictive. And prettier) / [Vicious Gladiator's Mooncloth Gloves]
You have a lot of alternatives for the hands. As long as it's black and doesn't destroy the sleeves of the chest piece, you're good. I prefer these two as opposed to the others as both have more interesting textures.
Feet: [Black Mageweave Boots] (BoE)
Available via Tailoring (230).
Same as the hands, you have a lot of alternatives for the footwear. If you want a better fit albeit more challenging piece, get [Saltarello Shoes] from Naxxramas (10M).
And this set thusly named because of this screenshot:
