He really just needs a casting director or PR person from one of these companies to come forward and explain the thought process...was there a test shoot? Did you not meet the model before you had her model 100 outfits for your website?
If these companies don't have casting directors and need one, Fashion by He is located in NYC and will offer his services FREE of charge. There is no excuse that anyone this size should be modeling on these types of websites.
P.S. He doesn't do this to offend the models, this isn't there fault, every model that has been called out is gorgeous, but not for these types of jobs, its the companies to blame.
