Fortunately for you, WoW Insider has prepared a simple makeover guide for your bank toon. If you've been treating your banker right, you've probably dressed them in the tuxedo sets made from Tailoring or obtained through the Noblegarden event. Complete the look with a perfectly matching pair of Frayed Shoes. You probably won't find these on the Auction House, but they drop from Level 1-5 mobs, so they shouldn't be a problem to farm. If you're too lazy (or unlucky), you can purchase Heavy Weave Shoes from clothiers in most cities. These also go very well with tuxedo sets but require Level 12. I personally keep my banker at Level 1 too keep her ego in check, so it's the Frayed Shoes for her.
