New Gods Costuming
The New Gods are dimly aware of all past, present and future fashions and can appear however they like. Normally they will dress to impress (because they're fabulous), but it can also helps them gather mortal worshipers (or get a divine date).
Pantheon members are encouraged to wear some matching items to help identify them.
Costuming is its own reward; it makes the game better for everyone.
