Burning Rage Plate Set
Level: Requires Level 85
Armor Level: Rare
Armor Type: Plate
Binding: Binds on equip
Crafted by: Blacksmithing
This is a great looking crimson red set. Unfortunately there were no pants with this set. The plans drop off specific mobs in Outlands.
Bloodthirsty Ornate Pyrium Plate Set
Level: Requires Level 85
Armor Level: Rare
Armor Type: Plate
Binding: Binds on equip
Crafted by: Blacksmithing
This set is the crafted plate PVP set for Pally healers, it is very pretty with the purple gems added to the set. You should be able to pick this set up on the AH for cheap because many Blacksmiths use it for leveling.
Mats: 97x Elementium Bar, 80x Volatile Water
Bloodthirsty Ornate Pyrium Belt
Bloodthirsty Ornate Pyrium Boots
Bloodthirsty Ornate Pyrium Bracers
Bloodthirsty Ornate Pyrium Breastplate

I love the color of this set.

Twilight Trappings Cloth Set
Level: Requires Level 60
Armor Level: Rare/Uncommon
Armor Type: Cloth
Binding: Binds on equip
Crafted by: Tailoring
This looks super hot. This set was part of quests in Silithis for the Twilight Cultists summonings. The quests are no longer in game, but the three cloth pieces for the set are.
Spiritmender Cloth Set
Level: Requires Level 81-83
Armor Level: Rare/Uncommon
Armor Type: Cloth
Binding: Binds on equip
Crafted by: Tailoring
This set is a nice pewter and blue color.

Netherweave Vestments Cloth Set
Level: Requires Level 75-77
Armor Level: Uncommon
Armor Type: Cloth
Binding: Binds on equip
Crafted by: Tailoring
This set reminds me of many of the Gilneas NPC’s in the Worgen starting zone. This set can be made very cheaply for transmogrification and tailors could make some money by putting this set on AH when 4.3 hits.
Mats needed: 33x Bolt of Netherweave, 8x Rune Thread, 3x Knothide Leather
Duskweaver Cloth Set
Level: Requires Level 75-77
Armor Level: Uncommon
Armor Type: Cloth
Binding: Binds on equip
Crafted by: Tailoring
This set used to be common in Wrath, partially due to the super low mats required to craft the complete set. You might be able to find this on AH by someone leveling tailoring.
Mats required: 70x Bolt of Frostweave, 10x Eternium Thread.
Deathspeaker Cloth Set
Level: Requires Level 80-81
Armor Level: Rare/Uncommon
Armor Type: Cloth
Binding: Binds on equip
Crafted by: Tailoring
Starter tailoring gear for Cataclysm, very common on the AH so you should be able to pick it up or craft it very cheap.
Mats needed: 31x bolts of embersilk cloth, 12x eternium thread, 9x volatile fire
The Postmaster Cloth Set
Level: Requires Level 45
Armor Level: Rare
Armor Type: Cloth
Binding: Binds on pickup
Dropped by: Postmaster Malown in Stratholme
One good thing about this set is you can keep running out and coming back to kill him again easily, until you hit your instance cap. You should be able to farm this fairly easily. Unfortunately, it takes a bit of work to get the boss to spawn, but fortunately, you no longer require the mailbox keys to summon him. You need to open three mailboxes and then the boss will spawn. He has a 20% chance to drop each piece. This will definitely be one of the lesser known cloth sets for those looking for unusual sets to transmog, because many people don’t know how to spawn this boss, or have forgotten how since this set became irrelevant.
Necropile Rainment Cloth Set
Level: Requires Level 40
Armor Level: Rare
Armor Type: Cloth
Binding: Binds on pickup
Dropped by: Bosses in Scholomance
This set is easily farmable by 85s but does have a very low drop rate so you will want to start farming this set sooner rather than later, and drag some guildie alts behind you to do all the looting for you 
The chest piece as a skull on the chest that looks pretty cool.
Imbued Netherweave Cloth Set
Level: Requires Level 67-70
Armor Level: Rare
Armor Type: Cloth
Binding: Binds on equip
Crafted by: Tailoring
This set can be crafted easily, but do we aware there are two chests for this set. This would be a good set to sell for tailors looking to make money when 4.3 hits because of the mats required, which are easily farmed or picked up for cheap on AH.
Mats needed: 270x Netherweave Cloth, 6x Netherweb Spider Silk, 30x Arcane Dust, 6x Knothide Leather, 3x Runethread
Frostsavage Battlegear Cloth Set
Level: Requires Level 78
Armor Level: Rare
Armor Type: Cloth
Binding: Binds on equip
Crafted by: Tailoring
This set can be a pain to get mats for, unless you luck out on AH either for cheap mats or a leveling tailor listing them.
Mats required: 27x Bolt of Imbued Frostweave, 33x Crystallized Fire, 33x Crystallized Earth, 16x Eternium Thread
Bloodvine Garb Cloth Set
Level: Requires Level 60
Armor Level: Rare
Armor Type: Cloth
Binding: Binds on equip
Crafted by: Tailoring
This set unfortunately requires items that were only in the old Zul’Gurub instance. The patterns were rep patterns from the Zandalar Tribe. If you love the set, watch for Bloodvine on the AH (I am thinking I have some of this kicking around in an alt guild bank somewhere) or the pieces themselves and snatch them up. This set has a leather-look to it, so it would have been popular for 4.3!
Wrath of Spellfire Cloth Set
Level: Requires Level 70
Armor Level: Epic
Armor Type: Cloth
Binding: Binds on equip
Crafted by: Tailoring
Another nice tailoring set with a nice design.
Total mats: 468 Netherweave Cloth, 52 Arcane Dust, 26 Primal Mana, 64 Primal Fire, 10 Netherweb Spider Silk
Whitemend Wisdom Cloth Set
Level: Requires Level 69-70
Armor Level: Epic/Rare
Armor Type: Cloth
Binding: Binds on equip
Crafted by: Tailoring
I always thought this would be great for toons with names beginning in V since that is always what this helm reminds me of. Only two pieces to this set, no chestpiece to go along with the helm and pants. It can be expensive to make, as Primals tend to be expensive.
The Unyielding Cloth set
Level: Requires Level 69-70
Armor Level: Epic/Rare
Armor Type: Cloth
Binding: Binds on equip
Crafted by: Tailoring
Only two pieces to this set.
Spellstrike Infusion Set
Level: Requires Level 70
Armor Level: Epic
Armor Type: Cloth
Binding: Binds on equip
Crafted by: Tailoring
I love the hood on this set, I only wish there was a matching chest to this set. Crafted by tailors, but because of the mats you likely won’t see this on the AH.
Soulcloth Embrace Cloth Set
Level: Requires Level 70
Armor Level: Epic
Armor Type: Cloth
Binding: Binds on equip
Crafted by: Tailoring
Another nice set with an interesting color scheme, but alas, Blizzard forgot to make pants to go with this set. You likely won’t find this one on the AH, so you’ll have to find a tailor that has these old patterns.
Shadow’s Embrace Cloth Set
Level: Requires Level 70
Armor Level: Epic
Armor Type: Cloth
Binding: Binds on equip
Crafted by: Tailoring
This is a gorgeous teal and pewter set for cloth wearers. Farming the primals can be a pain unless you manage to scoop some up for cheap on your AH.
Mats required: 234 Netherweave Cloth, 26 Arcane Dust, 13 Primal Shadow, 13 Primal Fire, 38 Primal Water, 8 Netherweb Spider Silk
Bloodthirsty Fireweave Cloth Set
Level: Requires Level 85
Armor Level: Rare
Armor Type: Cloth
Binding: Binds on equip
Crafted by: Tailoring
This crafted bloodthirsty set looks more warlock style. You should be able to find this on AH.
Bloodthirsty Embersilk Cloth Set
Level: Requires Level 85
Armor Level: Rare
Armor Type: Cloth
Binding: Binds on equip
Crafted by: Tailoring
The helm on this set screams warlock, but the colors on this set scream priest or mage. The set is pretty common and you should be able to pick it up off the auction house for pretty cheap from tailors.
Arcanoweave Vestments
Level: Requires Level 69-70
Armor Level: Rare
Armor Type: Cloth
Binding: Binds on equip
Crafted by: Tailoring
This is an interesting looking set crafted by tailors, and the mats are pretty low for the complete set. There are no pants for the set, but fortunately the chest is a long dress style to cover it up!
Mats needed: 156 Netherweave Cloth, 48 Arcane Dust, 6 Rune Thread
Reaver Plate Set
Level: Requires Level 64
Armor Level: Uncommon
Armor Type: Plate
Binding: Binds on equip
Dropped by: Level 60s mobs.
This nice black plate set is one you can pick up for pretty cheap. I don’t like the helm so much with this set, but you can easily find a replacement for it. This set drops with a random enchantment on it. You should be able to pick this up for pretty cheap on AH or go farm some Outland rep and watch the drops for these pieces.
Skettis Mail Set
Level: Requires Level 67
Armor Level: Uncommon
Armor Type: Mail
Binding: Binds on equip
Dropped by: Level 60s mobs.
This is one of my favorite mail sets, and you can usually pick up pieces off the Auction House pretty cheap since they are greens.
Stormshroud Armor Leather Set
Level: Requires Level 50-54
Armor Level: Rare
Armor Type: Leather
Binding: Binds on equip
Created by: Leatherworking
This set is crafted by leatherworkers. However, you will need to find a leatherworker who has this set, since only the pattern for the legs is available, the rest of the mobs were removed in Cataclysm. There could be an AH market for leatherworkers who can make this and farm the mats.
Full set requires: 44 Rugged Leather, 6 Enchanted Leather, 12 Essence of Air, 1 Cured Rugged Hide, 4 Ironweb Spidersilk, 2 Runethread
Primal Batskin Leather Set
Level: Requires Level 49-53
Armor Level: Rare
Armor Type: Leather
Binding: Binds on equip
Created by: Leatherworking
The status on making this set in Cataclysm is unknown unless someone with the pattern has mats still. The patterns were purchased with faction reputation levels from the Zandalar Tribe prior to the Shattering. It is unsure if this set is still craftable, since one of the items Primal Batskin was only skinned in the old Zul’Gurub. Unfortunate because the chest is pretty hot!
Ironfeather Armor Leather Set
Level: Requires Level 49-53
Armor Level: Rare
Armor Type: Leather
Binding: Binds on equip
Created by: Leatherworking
This set is bind on equip, but only two pieces to this set. You might be able to pick this up off AH for cheap.
Fel Skin Leather Set
Level: Requires Level 67-69
Armor Level: Rare
Armor Type: Leather
Binding: Binds on equip
Crafted by: Leatherworking
This set is bind on equip (some confused the Leatherworking set bonus to mean only leatherworkers can wear). Unfortunately there is no chest with this set, but the pants look great.
Embrace of the Viper Leather Set
Level: Requires Level 16
Armor Level: Rare
Armor Type: Leather
Binding: Binds on pickup
Dropped in: Wailing Caverns
This set is a pretty unusual look for leather wearers, especially the shade of purple. It is pretty unique as far as WOW outfits go. This set drops in Wailing Caverns off various bosses. Easily farmable with a 30% drop rate.
Devilsaur Leather Set
Level: Requires Level 40
Armor Level: Rare
Armor Type: Leather
Binding: Binds on pickup
Crafted by: Leatherworkers
Unfortunately there is no chest with this set 
Crafted by leatherworkers but because it requires Devilsaur Leather, you probably won’t find this on the AH.
