The 19-year-old, who got engaged to Hunger Games star Liam Hemsworth in the summer, explained that she is excited about seeing the groom when she arrives for their wedding.
Speaking on The Ellen DeGeneres Show, Cyrus explained: "What I'm most excited for is that look, when who you're marrying, you see the first time - you're seeing the dress and everything you planned for months and months coming together, and you did it together.
"And it's only the people that you really want there - it's a day that you don't have to say, 'Well, I'm kind of obligated...' I don't ever feel like that. This is the one day that it's what I choose and every detail is things that I love, and I think that look - I don't want people to ever forget about that."
She continued: "There's some rumour going around that I'm having like 47 weddings - I'm not. I'm having one wedding. That's my day and whatever I want on that day, it will be about me and that moment, that look of love."
Cyrus went on to say that she wants the moment to be "perfect" and "like the soundtrack in a movie", saying: "That's the one day that that movie crap is real, that romance. That look is the time that you get that. I've been to probably 10, 20 weddings and I've seen that look probably five, six times. It's rare that people just stop to really look a person in the eye and know that this is your life together. It's important."
Cyrus also revealed that she does not expect to marry Hemsworth just yet as she is currently busy with her music.
"I'm so focused on my recording that I don't want to be in between touring and trying to plan all that," she said. "I didn't really realise until I got a wedding planning book what you have to decide on. Like, I don't care what colour the napkins are, to be honest! I really don't care. So it's a lot of weird detail - I don't want to be doing too much and be crazy and forget about the moment of it all."
Cyrus was yesterday granted a temporary restraining order against a man convicted of trespassing on her property.
