My opinion about Thin models

I think the world's top models are improper,Everyone knows that designers hold fashion shows to want their designs becomeing a trend, It means that more people like their designs. However, there are only a few people tall and thin like the models,So I think their idea is wrong and it needs to be changed,Their design will suit the general public.SO designers choose the models must from general public, The event of the model killed on the runway will not happen.
