Requesting a charity contribution rather than a gift: It is very poor wedding invitation etiquette to even mention gifts but most invited guests will enquire if there is a wedding gift list. The other members of the wedding party should be encouraged to put the word around as to what the bride and groom would prefer.
Making the right choice _ There is also no "right" choice when designing your wedding invitation. There is no one color that will look acceptable. Many people choose colors from their wedding theme to help coordinate the look of their wedding, but that is not necessary. It is more important that you choose a look that you love. The wedding invitation is a lifelong keepsake of your special day.
