If you’re a groomsman getting ready with the husband before the big day, can you post photos of him putting on his suit and tie to your Instagram story? Should bridesmaids document their glam before they walk down the aisle? It’s fine and good to take photos during wedding prep, but they should not be posted online before the wedding actually occurs. And while you can take a photo here and there of the ceremony, livestreaming the wedding without the couple’s consent or trying to play wedding photographer (when the couple has already hired one) is rude. You can wait until after the wedding is over to put it on social media. And knowing how to navigate social media is just one of the modern etiquette questions you need answered.
