I don't have any I can share, but check out Google Images... just plug in "Cast Member" after the attraction's name.
For Expedition Everest, their Cast Members wear multi-colored pin stripe/patterned button-down shirt that has a patch with attraction insignia and black shorts/pants that have colored stripe swatches. Rock'n Rollercoaster Cast Members wear a "parking attendant" costume, with black pants, a button-down with various notes and a red vest that has a patch with attraction insignia. RnRC also has black coats available. For Big Thunder Mountain Railroad, their Cast Members wear a light red-dirt colored western-style collared shirt and brown pants.
Most attractions shifts require that you have current training for that particular attraction, although it does vary. PAC shifts can be picked up by attractions Cast Members.
