Cyrus, 20, is apparently considering a gown from designer Marchesa for her big day but she said this probably will not be the only designer that she will be wearing on the day, reported People magazine.
"Marchesa make the most amazing dresses, they are definitely one of our options. But so many people want to be involved, I'll probably have 30 dresses at my wedding," she said.
While she is struggling to choose the right dress, Cyrus also says that she and her fiance are not getting stressed about the wedding planning.
"I'm not worried about it, we haven't talked about anything specific. Liam is pretty laid back about everything, it's the best thing ever," she said.
