Have been invited to several ceremonies for a Hindu wedding. Ths ladies willsbe wearing saris but I'm not a Hindu. There is a marriage ceremony in the morning and lunch. Then an evening wedding reception with dinner, all in a very posh venue. Do I change? Should I wear short dress am and a long dress pm? Also an invite to their home from the brother of the bride for an evening of Mehndi, music and masti and a morning ceremony the next day before the wedding day. Any ideas from those who have knowledge of hindu weddings including colours to avoid. Don't want to offend anyone.
