Quinceanera

Hello. My name is Alyson and I am turning 14 in a few months. I would love to have a quinceanera but I have no idea where to start. I would be interested in finding out informtaion about the average cost of a quince, as well as some traditions that are still popularly used today. I also have a few questions about the dress. I`ve heard that a white quince dress is traditional, but many mothers don`t want thier 15 year-old looking like brides, and opt for a pastel-colored dress. Does this depend on your country`s traditions? Also, are there any themes that are pretty, but can still be made personal? Thank you so much for your help, I really have no idea where to start.
