So its our five year anniversary and we are doing a vow renewal. My dress will be lilac and my maid of honor will be wearing dark purple, as is the color theme for the event. What is the best way to put on the reception card/invite that people not wear purple? I dont want to just write "Dont wear purple" cause obviously that seems rude, but I really dont want anyone matching me or my Maid of Honor, its basically the same principle as someone not wearing white to a wedding, only that usually goes unsaid so ugh Im stuck and need help.
