How do you become a wedding dress model?

Same way you become a regular model. You have to contact an agency or find designers who can set upphoto-shootsfor you to get you started. You should create a portfolio first of any modeling shots. You can find a photographer who maybe needs work for their portfolio too and you can work with them. If you are willing to you can also pay a photographer of course.

Another option is taking the photos yourself with a timer and tripod if you have a good camera. It's certainly not easy and you will get turned down by some and of course you have to be a certain size. Usually 120 pounds or less and 5'7 and up. Wedding dress modeling may have more wiggle room for height though but i'm sure not much.
