the costume worn by the dancers. Each team designs its own kit, which usually starts with a white shirt and leather pads covered with bells and (sometimes) ribbons. Everything else is variable and distinctive of a team. In Cotswold morris, dancers wear white or color trousers or britches ("knickers" for you Yanks), and either a colored vest or tunic or baldrics (ribbons crossed over the chest) with arms and legs decorated with bright ribbons. In Border morris, the kit is a bit wilder and usually consists of strips of cloth, usually called tatters or rags, sewn all over a shirt, jacket and/or trousers. Dancers often "black up" -- ie, wear black face as a form of ritual disguise. In this age of political correctness, however, many teams skip this or else wear clown makeup or masks instead
A game kit is the PCB with one or more items. A complete kit would contain everything but the game cabinet proper (PCB, CPO, Side Art, Marquee, Bezel, wiring harness). Partial kits are the norm, usually a PCB and a marquee.
