Underweight models

I think that is very good idea to set a standard to keep model's BMI level. I heard some model are taking drug to lose weight. Some are suffer from anorexia. Some of people are born to be skinny but some are not. I think it is quite silly to destroy their own health to keep themselve to be skinny. I think helth is most impotant things. Many young girls admire models on the catwork. I 'm afraid they might want follow model's life style and eaven sacrifice their life. In my opinion, models are not nessesary to be underweight. As long as they are healthy, looking good in most kind of clothes.
Desighner also should think about consumer. Consumers are not all one size. If they choose underweight models, consumer might take that is a standard of beauty. I think women in a picture of Renoir is beautiful but I don't think Munch's one is beautiful. Decadence beauty is out of fashion.
