Sisters and brothers share a unique bond, since they bring different perspectives and experiences to the relationship. Nevertheless, your brother's wedding day is a chance for you to craft a very special brother wedding card message, reflecting on your unique relationship and sharing in his happiness. Once you've got that down, you can work on your brother-sister wedding dance or sister-of-the-groom speech.

  • As your sister, know that you can always come to me if you want to talk, or need advice on how to keep your [husband/wife/spouse] happy and feeling supported. Congrats to you both!

  • Mom and dad sure got lucky with us, didn't they? I know they'll welcome your [wife/husband/spouse] and feel lucky to have [him/her/them] in their lives, too. Congratulations and best wishes for a happy future together. I can't wait to be a sister-in-law!

From One Brother to Another

No matter your birth order, these happy wedding wishes for a brother are just right for this special occasion. Whether your relationship feels more like a mentor-mentee one or you're just two peas in a pod, don't hesitate to tell your bro what makes your bond (and him) so special.

  • Brother, you're about to embark on an amazing journey—trust me. May you enjoy every moment of married life.
