I can say that now, since it's actually advent (unlike when retail stores started putting up decorations back in October. Or was it September?). Our town's annual tradition starts December with the Candlelight walk and Christmas carols, leading up to lighting the lights along the creek and main street through town.
Our bellydance troupe joins the fun, since we dance every First Friday anyway! I made the elf hat (freehanded for lack of a suitable free pattern) for the occasion :)
