“My older sister is my best friend! Would it be acceptable if she were the Best WoMan at my wedding?”
Groom’s Etiquette Expert, Chris Easter’s Answer:
Grooms, this is a lot more common than you think. Selecting your Best Man is all about finding the person that you want standing beside you on one of the most important days of your life. If this happens to be your sister, you shouldn’t let perceived standards hold you back. Your wedding is about you, so you should absolutely ask your sister to be Best Man (or WoMan). Although I do recommend letting her wear a dress instead of a tux!
