The number one thing you should know about your wedding is that it’s simply a day when anything and everything could happen. No matter how many times you cross things off your to-do list, triple confirm with your vendors, and do a no-rain dance around your apartment, you never know the twists and turns that’ll knock on your door during one of the most precious and important days of your life. So if you’re looking to take a proactive approach to fighting off any pop-up disasters on your wedding day, here are 5 that you can easily avoid.

1. Vendors Are a No-Show

There are a lot of moving pieces when it comes to planning a wedding and often those moving pieces involve your wedding vendors. Even if you’ve been chatting with them for months, have one member of your bridal party call them at 9am on your wedding day to confirm their arrival. Ask them to show up 30-45 minutes before the time you truly need them there. That buffer period will allow for traffic and any other hiccups.

2. You Run Out of Food

You don’t want to have to face a couple hundred hungry guests when you run out of food at your buffet or even during cocktail hour. Always order a little more food than you need or add-on a late night snack bar.

3. The Dress of Your Dreams is a Nightmare

If you’re having trouble fitting into your wedding dress, whether it’s too big or too small, make sure you bring some fashion emergency items with you, including a mini-sewing kit, double-sided tape, and safety pins.

4. Your Flowers Make You Sneeze

If you suddenly realize that you’re allergic to the flowers you picked, try to avoid holding your bouquet until it’s time to walk down the aisle. Keep it at a bit of a distance from your chest and face and hand it over to your maid-of-honor before it’s time to kiss the groom.

5. The Power Goes Out

If the power goes out and the venue doesn’t have a backup generator, the only thing you can do is make the best of the situation. Send someone to the nearest convenience store to pick up candles and move the party outdoors.
