I am helping a friend plan her daughters wedding and we have a problem. The ceremony isin a church, the bride and groom are dressing formally as are the attendants. The reception is outside with a tent, lighting, linens, catering, etc. The problem is, that even though the grooms family is aware of all this, they have declared that "it's just an outdoor party" and are planning to wear jeans. How do we word the invitations to reflect the mood of the event?
