For example, formal wedding invitations in cream and gold can inform your guests about the formality of the event. It is important for them to know if your wedding is going to be traditional rather than casual. In contrast, if you send your guests contemporary invitations in bright colors, they should know to expect something a little more casual. On the other hand, if your unique wedding invitations are of a particularly unusual design, chosen to reflect your own personal style as well as the style of your wedding, your guests may know they can expect something nontraditional.
Is it acceptable to have a unique wedding invitation even if you are planning a traditional wedding? Absolutely. While some people like to coordinate their invitations with the style of their wedding, it is not strictly necessary. If you have a fun or different idea for your wedding invitations, then, by all means, choose the invitation that you want. If you plan on celebrating with a formal ceremony, make sure to mention that on the invitation, such as "black tie requested". On the other hand, if the wedding invitation is off_beat people may assume that your wedding will be a more casual affair unless you specifically state otherwise. Putting the information on the wedding invitation prevents any confusion.
