My dear friend (mother of the groom) is not allowed to invite any friends to her son's wedding, and only a few relatives (even though they tactfully offered to share the expense of the reception), and every aspect of the wedding (and rehearsal dinner that they are hosting) has been planned contrary to any wishes of her family. Would it be appropriate for a few of her friends to host a small luncheon honoring her and the upcoming wedding? It would be tasteful and loving...with the intent of surrounding her with love and a 'send-off' to the wedding festivites?
