But one thing that's completely out of your hands is the crazy thoughts you'll think when you start walking down the aisle.
Usually, that's the moment you're probably hoping you don't trip and fall or suddenly get a raging case of cold feet and become a runaway bride.
But it's also a huge, pressure-filled moment. Being engaged can feel like a fairy tale of fun, but actually going through with a marriage can bring out a lot of truths — for better or for worse.
Read on below for some funny, scary and even strange thoughts that went through real brides' heads right before they said, "I do":
1. What the hell am I doing?
I feel like I walked down the aisle and practically blacked out. But the only thing I remember thinking, when I looked around at all the guests and at my dress, was what the hell is going on? And what am I doing? It's not because I didn't love the person I was marrying. It was more that I never wanted to have a girly, princess-like wedding, and here I was having one.

2. I think this feels right?
I don't know how a person is supposed to feel when they are walking down the aisle, but I remember wondering if I was supposed to feel head-over-heels in love. I kind of just kept thinking, 'I guess this feels right,' but I wasn't 100 percent sure of that.

3. Can everyone please stop looking at me?
Walking down the aisle made me feel like a celeb. Everyone turned to look at me and pulled out their phones and cameras to take a pic. I think I would have felt less nervous if everyone was seated and just looking forward. I wanted everyone to please stop looking at me. I felt like that until the reception started.

4. I need a Xanax.
Right before the wedding started, the nerves kicked in, and I couldn't chill out. As I was walking down the aisle, I really wanted to ask a friend of mine, who was a wedding guest, if she had a Xanax. It would have been a life-changer.

5. I hope I look good in these photos.
I had spent, like, six hours before the wedding taking pictures and stuff with my full makeup on. When everyone was taking photos of me walking down the aisle, I selfishly kept thinking about how I would look in their photos, and I was hoping I'd look really good.

6. I don't know about this.
I had major cold feet walking down the aisle. It hit me that this might not work. Like, I hope it does, but there's a chance I'll get divorced, and I'm not even married yet!
