When you first wake up, take a few moments to yourself to think about what this day is all about. It will feel a little surreal and so wonderful.
Take an extra luxurious shower that morning.
Save lots of time for getting ready. You don't want to have to hurry through putting on your dress, your shoes, your jewelry. Relish this time and make sure everything is perfect.
Allow your bridesmaids to do things for you (hold your purse, track down this person or that person, put your bouquet in a safe place at the reception). It will keep you from becoming frazzled and they'll be happy to help the bride.
Give your parents a few extra hugs and thank them--for everything.
Memorize the look on your groom's face as you walk toward him down the aisle.
Really savor the beauty of your vows, the beauty of the music, the beauty of your love being witnessed.
Show off your shoes.
Notice your guests' smiles and laughter and bright faces and remember that it's all in celebration of your new marriage.
Remember how blessed you are to be marrying this man on this day.
Eat a full piece of wedding cake.
Find your parents again and hug them.
Most of all, fill yourself up with all of the love of the day. Your wedding day is about uniting two souls in love, and each moment will be beautiful.
