Quetzalcoatl: Nerd chic. His wardrobe's mostly button-down shirts all the better for Coyote to tear off and slacks, since 1.) he likes them, and 2.) he tries to look professional. He's got a few pairs of jeans and T-shirts, but you're more likely to find him looking like, well, a college professor. He has a shameful amount of sweater vests.
Osiris: Wears nothing but long sleeves and pants, to cover the scars from when he was cut up. Owns a few suits for any formal events, but he tends to be found in jeans and long-sleeve T-shirts. His shoes are mostly sneakers, all of which are somewhat ratty/water-logged, but very comfortable. He wears jackets often, since he gets cold easily. All of his clothes are dark colored, mostly shades of blue, black, and green.
St. George: Dresses very casually. He's a T-shirt guy through and through. He prefers jeans or cargo pants with lots of pockets, and is usually either in work boots or sneakers. He likes heavy jackets, and loves his camo one best. A good portion of his wardrobe is actually camouflage, but the stuff that isn't tends to be brightly colored. He also has the uniforms (combat and dress) from all five branches of the military, as well as the National Guard.
Lizzie Borden: She likes to dress provocatively. Low-cut sleeveless tops, skirts with slits in them, and tight jeans. When she's giving tours at the bed and breakfast, she'll usually wear longer, more flowing skirts, but in her personal time she prefers to show a lot of skin. She's got several leather jackets.
