Easy on the gifts
If you're scanning the registry and it's a choice between the vintage tea set on a distressed mirror for a gajillion dollars, or the dish towels for a more comfortable six bucks, swing cheap. Weddings are expensive AF and if you've got a lot of them on your dance card you want to be sure you still have money at the end of the season to spend on things like… you. Budget what you can for gifts and then say 'fuck it.' You're living on a single person's income, and chances are that's not a lot.
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.
Easy on the sauce
A wedding without an open bar is no wedding at all, we say! That said, a wedding is not really the time to race to the bottom of the barrel. It won't be as funny the next day that you twerked in front of Uncle Buster, made a toast to yourself finding happiness, or you know, cried.
