My daughter-in-law conducts a wonderful Seder every Passover, complete with traditional foods, readings, special family linens and silver - a really nice event. It contains many non-traditional elements as well, such as English language passages added to the original readings to acknowledge and commemorate certain present-day blessings and hopes. Friends of all faiths participate, and there's plenty of wine so most folks end up a little rowdy - it's a mix of Orthodox and highly unorthodox people and things.
My question is: what does one wear to such a function so that one's clothing reflects its joy and celebration as well as respect for the hostess and the religious aspects of the occasion? I always feel a little embarrassed for the peeps who show up in super-casual garb and then see how much trouble my DIL has gone to for this meal.
