1. Remember what's important
Once the big day arrives, there won't be much you can do to change what happens. At the end of the day, you get to be married to the love of your life.. so don't sweat the centerpieces.
2. Make sure someone know's how to get you into and Bustle your dress
Some bustles are COMPLICATED. Have your maid of honor or mother take notes at the bridal salon or draw a diagram so you aren't spending an hour trying to figure it out while your guests enjoy your reception.
3. Have a day of coordinator
If you can hire someone to handle the details on the actual day, it alleviates so much stress. You and your family should be able to enjoy the day rather than coordinating vendors or setting up the ceremony space.
4. Do a First Look.
I understand wanting to be traditional, but having a few moments alone with your husband to be before the wedding will not only calm your nerves....but allow you to complete most of the photos prior to the wedding. Once the "I Do's" are done you can celebrate with your guests rather then spend hours on photos.
5. Don't leave right away for your honeymoon
Taking a few days or a few weeks after the wedding to leave for your honeymoon will take away a TON of stress. You don't want be packing for the wedding day and honeymoon in the same week. You will also be able to enjoy your evening rather than worrying about waking up for an early flight.
