What clothes does the mother-in-law wear?
Customs vary from place to place. I come from Guangxi and have attended several weddings. My mother-in-law and mother-in-law are usually red silk coats or burgundy clothes. Anyway, it should be red, regardless of style, brand and style. Just wear something festive. Usually when you get married, your daughter and son-in-law give you clothes, and your mother-in-law can wear cheongsam.
