A generally non-Transmogrification-friendly collection of outfits worn by characters who have accumulated /played far beyond what would be normally expected for their level due to spending most of their time running between the mailbox, the Bank, and the Auction House. I will update it sporadically as I create new Banking outfits. Items that are no longer obtainable are marked with an asterisk (*).
Formal Black and White
Elemenatlist Skullcap, Shadow Council tunic & trousers, Silver-Thread Sash, Antique Silver Cufflinks, Bandit Boots, Warmonger’s Cloak, Black Ice
Even without the Black Ice ring, this outfit requires a quite high-level character.
I don’t always display the hat.
The Black Mageweave Vest + Formal White Shirt would be a nice variation in place of the Shadow Council tunic.
Haliscan Bard
Haliscan Brimmed Hat/Forever-Lovely Rose, Haliscan Jacket & Pantaloons, Bard’s gloves & boots, Warmonger’s Cloak, Tuxedo Shirt, Dazzling Mithril Rapier
Even though the brick red of the cummerbund and the maroon of the boots & gloves don’t match exactly, I am absurdly fond of this combination.
Thunder Bluff Banker
Bloodwoven chest belt pants & bracers, Khadgar’s Knapsack
For a short time, the Bloodwoven chestpiece appeared as an elongated tunic, like the Journeyman’s Vest, and I was very distressed because I no longer looked exactly like the Thunder Bluff bankers in this outfit.
Thunder Bluff Auctioneer
Resilient tunic belt pants gloves & boots, Talhide Helmet, Chieftain’s Shoulders, Amber Cape, Ramkahen Ceremonial Hammer
I’d been wearing the base set for a few days when I was browsing the AH and was struck by how nicely this hat matched. With a hat, I needed some shoulders, too.
This weapon not only coordinates well with the set, but also amuses me because it matches the one given as a pestle for grinding corn for the Corn Mash cooking daily in Thunder Bluff.
Chief Officer of Finance
Durable jacket, Tuxedo Pants, Dress Shoes, Tuxedo Shirt, Antique Silver Cufflinks, Spring Gadget
The other zeppelin captains and chief officers are wearing the dusty green Conjurer’s Vest and the dark blue Sorcerer Drape. Kazuliza has all the colors of this chestpiece in her inventory, though she can’t wear them all just yet.
Keeping House
Seer’s Padded Armor, Godfrey’s Britches, Reconnaissance Boots*, Farmer’s Broom
Kymberlea leaves her kids with “Nana Morene”, her mother’s best friend, when she goes out questing.
Tux and Top Hat
Top Hat, Tuxedo jacket pants & shirt, Dress Shoes, Diamond-Tipped Cane
Although she was ultimately intended to be a Gnome all along, Karrieanna began her existence as a Worgen specifically so that I could later do this. I wish she could wear both a top hat and a monocle at the same time, like Fineas G Bankworthy.
Cow in Wolf’s Clothing
Gilnean Acolyte’s Robe; Gilnean Footpad’s tunic & gloves with Gilnean Tracker’s pants & boots; Gilnean Recruit’s set; Lord Walden’s Top Hat, Staff of Earned Tranquility
Same song, third verse… 
I don’t know if it’s because Karrieanna’s a Gnome or if it’s the hat, very clever planning! She’s wonderful!
She’s awfully cute, for sure!
