Plus Size models are getting there way into the modeling business, it has been a hustle for them and since my mother is of a plus size I do understand their struggles. I am glad to see retail is going more plus size and even at H&M there is a plus size section. It is inspiring because it can also mean there are more opportunities for the petite models. I plan on contacting some retailers and asking, why don't you have more petite sizes, considering that the average girl in America is 5'3"?
There is a website called Petitemodel.net
and also there is plusmodels.com if you want to check them out.
For the plus size model when you google Plus Size model there really isn't enough.
