A little vanity never hurt anyone (said no Disney villainess ever). Just because it's TECHNICALLY the bride's (ahem, bride and groom's) day that doesn't mean you can't bring your A game. Like we said, weddings are potential gold mines for meeting other single people and possibly having sex with (er… marrying?) them down the line. Go ahead and treat yourself to that outfit or haircut. You can still enjoy these things AFTER the wedding.
Stay off Facebook
For the love of God. When it comes to wedding season, Facebook is the WORST. Not only do you have to see photos of the wedding you were JUST at, but you have to see the photos of all the other weddings you weren't invited to and therefore thought you could happily avoid. That's cute that you thought that.
Starry-eyed couples also like to use the platform to post about their engagements as they are happening, right before they happen, after they happened… and then each subsequent event from engagement photos, to wedding planning, to the bachelorette. Every detail, save the actual consummation of the marriage, is cataloged. It's unlikely these egregious Facebook offenders will ever stop, so for the love of God, just stay off Facebook.
