Wedding etiquette has become even more complicated thanks to social media. Not only do you have to worry about buying an appropriate gift, but you have to make sure your tweet doesn't offend the bride. Thankfully, David's Bridal Canada did a survey of Canadian brides to find out what their social media rules are for their wedding. No pre-wedding selfies The #1 social media rule for weddings is no one and I mean no one is to post a photo of the bride before the wedding starts. This makes complete sense, part of the magic of a wedding is that moment where all the guests stare in awe as they see the bride for the first time. It's a beautiful moment that shouldn't be ruined by a pre-wedding selfie. I would also advise the bridesmaids not to post any pre-wedding selfies of themselves. The bridesmaid dresses aren't the star of the wedding, but they're definitely the runner up, so don't ruin the surprise by posting a selfie for all your friends to see. You may face the wrath of the bride if you do. Post-wedding photos are fine If you take photos of the wedding on your phone, feel free to post them to social media. Only 26 percent of Canadian couples believe they should be the first ones to post wedding photos to Twitter, Instagram and Facebook. And only 6 percent of couples restrict social media posts. I suggest you ask the couple before posting anything, just to make sure they are okay with you posting. Or maybe couples could just write on the invitation "Taking your own photos is encouraged." Though that seems a little weird. But I guess it's just a side-effect of living in a digital age, invitations not only tell you where the wedding is, but if you can Instagram there. #NoWeddingHashtags Thankfully, only 10 percent of couples said you have to use their wedding hashtag when posting to social media. Personally, I find wedding hashtags tacky. Your wedding is not the Oscars, people aren't following it for updates. Please, no more wedding hashtags.
